| 
|
NEi
Nastran V9.1 is a major upgrade with over 80 customer
driven enhancements.
Major
features include support for automated impact analysis,
enhanced nonlinear and dynamic solutions, improved
solver and overall performance, and new aerospace,
maritime, and automotive productivity tools. The NEiEditor
GUI has been modified to enhance the user interface
usability. Also, several other NEiEditor enhancements
have been included such as grid point stress and grid
point strain display, capability to move through the
same composite result measure ply by ply, and the
ability to restore default settings in the Setup property
page. |
| |
Added
support for a new Parallel Sparse Solver
(PSS):
Added support for the PSS parallel
linear equation solver in all solution
sequences via the DECOMPMETHOD directive.
This solver may be significantly faster
than the existing VSS, VIS, or PCGLSS
solvers. The PSS is supported on Windows
x64 and Linux platforms currently with
Windows IA-32 support to follow shortly.
Like the PCGLSS, is a high-performance,
memory-efficient equation solver capable
of handling large sparse matrixes on
shared-memory multiprocessors. |
 |
|
| |
Improved
nonlinear transient and nonlinear static solution
performance:
Improved nonlinear transient and nonlinear
static solution performance as much as 20x.
The most significant performance gain is with
models which are mainly comprised of linear
elements (shell and solid elements without material
nonlinearity) and with large displacement effects
turned off and models with velocity dependent
damping elements. |
| |
Improved
PCGLSS solver performance:
Improved PCGLSS direct solver modes
and Lanczos eigensolver performance. Additionally,
increased the maximum number of Lanczos extraction
modes to 7000. |
| |
Improved
transient and frequency response solution performance:
The following areas affecting performance
in transient and frequency response analysis
have been improved:
| •
|
Rod,
pipe, bar, and beam element processing. |
| •
|
Load
vector assembly processing reducing
total analysis time as much as 10x in
cases with large numbers of TLOADi and
RLOADi Bulk Data entries. |
| •
|
Large
models with large numbers of output
steps (greater than 500) reducing total
analysis time as much as 5x. |
|
| |
Improved
eigenvalue extraction performance:
Improved eigenvalue extraction convergence
in nonlinear prestress buckling solutions when
differential stiffness is requested (PARAM,
LGDISP, ON). |
| |
Improved
performance for random response solutions:
Improved performance for random response
solutions that:
| •
|
Referenced
multiple uncorrelated inputs. |
| •
|
Requested
vector output at discrete points which
included forces of single and/or multipoint
constraint. |
|
| |
Increased
performance by loading parts of the model database
into memory:
Made significant performance improvements
by loading additional sections of the model
database into RAM. Also, modified PARAM, DATABASEACCEL
options to include an AUTO setting. Now, when
DATABASEACCEL is set to ON, the model database
will be loaded into memory regardless of available
RAM. When set to AUTO, RAM availability is checked
for files that could use large memory blocks
and only if sufficient RAM is available, will
load into memory. |
| |
Reduced
processing time for element strain energy results:
Reduced processing time for element
strain energy results when grid point force
balance results were not also requested. |
| |
Improved
Nastran Binary and XDB file generation performance
and compatibility:
Better support is now provided for
both the Nastran Binary (.OP2) and .XDB results
neutral files. Support is now provided for most
element types and solution sequences. Additionally,
better translation performance for large models
with a large number of output steps is also
provided. |
| |
Reduced
subcase combination processing time:
Reduced subcase combination processing
time (SUBCOM). |
| |
|
|
| Linear
Analysis Enhancements |
| |
Added
linear surface contact analysis for linear static
solutions:
Added linear surface contact analysis
for linear static solutions via the LINEARCONTACT
model parameter. Linear contact is supported
in linear static analysis using surface contact.
Convergence takes typically 2 – 3 iterations
resulting in very fast analysis times on the
order of a 3 subcase linear static analysis.
PARAM, MAXLNCONTACTITER is provided to specify
the maximum number of contact iterations and
PARAM, LNCONTACTITERTOL to specify convergence
tolerance. |
| |
|
|
| Nonlinear
Analysis Enhancements |
| |
Added
support for large strain hyperelastic
materials:
Added support for large strain
hyperelastic materials via the PLSOLID
and MATHP Bulk Data entries. Support
is provided for the Neo-Hookean, Yeoh,
Mooney-Rivlin, and generalized polynomial
form of up to order 5, applicable to
nearly incompressible elastomers. Additionally,
the Ogden generalized polynomial form
of up to order 3 is supported. |
 |
|
| |
Added
Automated Impact Analysis (AIA):
Added Automated Impact Analysis via
the IMPACTGENERATE Case Control command. This
is a sophisticated tool which now allows the
user to define a remote projectile or impactor
and a target body without any preprocessor setup.
Input consists simply of the direction of travel,
initial velocity, and acceleration. The effective
directional natural frequencies of the impactor
and target in the contact state are calculated
internally without any user setup. The critical
time step calculations are then automatically
carried out based on these responses providing
a precise initial time increment and duration
of the analysis. Accurate time step prediction
is essential in calculating the magnitude of
peak response and maintaining an energy balance
during the contact event. Optional user defined
time increment and duration may be specified.
Additional control of output is provided via
the MAXIMPACTSTEP model parameter. The internally
calculated initial time increment will provide
very high accuracy, however the total number
of output time steps may be very large for a
long duration, soft impact analysis. MAXIMPACTSTEP
applies an override to limit the amount of response
data so that the user can reevaluate the analysis
feasibility. |
| |
Added
user definable restart capability for nonlinear
static analysis:
This is a very significant productivity
improvement for nonlinear users. A unique nonlinear
database has been created to allow very efficient
storage and retrieval of data during a nonlinear
analysis. Restart capability for nonlinear static
analysis is provided via PARAM, NLINDATABASE
and the NLINDATFILE directive. Multiple restart
database files may be generated at user defined
load increments which can then be used as restart
points with different loading, boundary conditions,
model parameters, and material properties. One
application could involve nonlinear buckling
(SOL 180) where the user can predict the load
region where instability is expected and confirm
it with a nonlinear buckling analysis. |
| |
Improved
stability, performance, and accuracy of welded
contact:
Improved stability, performance, and
accuracy of welded contact in nonlinear solutions. |
| |
Improved
surface contact weld element results:
Improved surface contact weld element
results for cases with large shear loads on
stiff parts. Model with surface contact welds
now run faster and give more accurate results. |
| |
Added
a new offset weld for surface contact:
Added a new weld form for surface contact
which allows large gaps between contact surfaces
while still providing accurate results and fast
convergence. The new weld form permits any size
gap between parts without introducing internal
constraints. |
| |
Enhanced
Automated Surface Contact Generation (ASCG)
for parts with large gaps:
Enhanced Automated Surface Contact
Generation when contact is between parts with
large gaps. Now gaps caused by midsurface meshing,
joint slop, or bush tolerances can all be handled
including weld elements using the new offset
weld element capability. |
| |
Added
a new parameter to convert surface contact weld
elements:
Added PARAM, SLINEOFFSETTOL which specifies
the tolerance for converting surface weld elements
to offset weld elements. |
| |
Added
a new parameter to specify a stabilization stiffness
between contact surfaces:
Added PARAM, SLINESTABKSFACT which
when set to a value greater than zero will add
a stabilization stiffness between contact surfaces.
The default zero value disables this feature.
A value of 1.0 will add a stiffness approximately
equal to the closed gap stiffness value. This
feature is useful in stabilizing contact with
a large separation between contact surfaces. |
| |
Added
a new parameter for surface contact nodal stresses
calculation:
Added PARAM, SLINESTRESSLOC which specifies
the location where surface contact nodal stresses
are calculated: SLAVE, MASTER, or BOTH. |
| |
Improved
automated surface contact generation:
Modified automated surface contact
generation to skip the generation of contact
surfaces that have excessive initial slave node
penetration, thus avoiding an E5072 warning. |
| |
Added
support for grid point results at points with
surface contact:
Added support for grid point results
at points where surface contact results were
also requested. Previously, grid point results
were skipped at surface contact grid points. |
| |
Improved
contact forces and stresses:
Improved accuracy of surface contact
forces and stresses for coarse meshes and unsymmetric
contact. |
| |
Added
new Automated Surface Contact Generation statistical
information:
Added Automated Surface Contact Generation
statistical information including contact area
generated. |
| |
Added
a new weld form for surface contact:
Added a new weld form for surface
contact which uses multipoint constraints (RBE3
elements) to connect contact surfaces. |
| |
Added
a new parameter for repositioning contact elements:
Added PARAM, NCONTACTGEOMITER which
specifies the number of iterations for repositioning
contact elements with initial penetration and/or
protrusion. |
| |
Added
a new parameter for reducing solution time for
nonlinear surface contact:
Added PARAM, SLINEMAXACTRATIO which
when set to a value greater than zero, specifies
the ratio of activation distance to contact
surface maximum edge length. This parameter
may be useful in reducing solution time for
nonlinear surface contact models by deactivating
contact segments far from area of active contact. |
| |
New
options for PARAM, CONTACTGEN:
Added GENERAL, WELD, SLIDE, ROUGH,
and OFFSET options for PARAM, CONTACTGEN. Integer
values may still be used. |
| |
Added
a new parameter to control the nonlinear differential
stiffness update strategy:
Added PARAM, NITERKSUPDATE which controls
the nonlinear differential stiffness update
strategy. |
| |
Added
a new parameter which specifies the number of
modes to be extracted during the automated impact
analysis:
Added PARAM, EMODES which specifies
the number of modes to be extracted during the
initialization phase of automated impact analysis.
A normal modes analysis is performed to determine
the damping frequency of interest and the time
step size. |
| |
Added
more control on line elements used in material
nonlinear analysis:
Removed PARAM, NLMATSFACT control
on line elements used in material nonlinear
analysis. Line elements with stress-strain curves
that have zero or negative slopes will now default
to 1.0E-10 times the elastic value when a slope
less than this value is encountered. |
| |
Added
large displacement and rotation effects for
CBUSH and CBUSH1D elements:
Added large displacement/rotation
capability for CBUSH and CBUSH1D elements with
non-coincident grid points and with an element
coordinate system defined by end grid points. |
| |
Improved
eigenvalue extraction convergence in nonlinear
prestress buckling solutions:
Improved eigenvalue extraction convergence
in nonlinear prestress buckling solutions when
differential stiffness was requested (PARAM,
LGDISP, ON). |
| |
Added
a new parameter to output nonlinear true stress:
Added PARAM, NLTRUESTRESS which when
set to ON will output nonlinear true stress
which accounts for change in element shape due
to deformation. |
| |
|
|
| Dynamic
Analysis Enhancements |
| |
Added
Bulk Data entries for shock and vibration
mount support:
Added TABLEVF and PMOUNT Bulk
Data entries for shock and vibration
mount support. This allows a fully coupled
description of a shock mount response
from test or theoretical series equations
to be defined. The velocity dependent
stiffness terms can be included. |
 |
|
| |
Added
mass and stiffness DMIG support for the PCGLSS
solver:
The PCGLSS linear equation solver (DECOMPMETHOD=PCGLSS)
and Lanczos eigenvalue extraction solver (EXTRACTMETHOD=LANCZOS)
now support DMIG input. |
| |
Increase
the hard limit for nonlinear transient output:
Increased the maximum number of nonlinear
time steps in nonlinear transient solutions
from 100,000 to 1,000,000. |
| |
Added
single point constraints forces to the Modal
Database for modal restart:
Added PARAM, MODEFSPCSTORE which when
set to ON will store single point constraint
forces in the modal database file for modal
restarts. When set to OFF and a modal database
restart is performed, single point constraint
forces will be calculated, if requested, using
the subcase 1 SPC set. |
| |
Better
support for the SET command in transient and
frequency response solutions:
Improved the use of SET commands with
real numbers for use in controlling transient
and frequency response output. Previously set
values were truncated to integers. This enhancement
is particularly useful when using response data
from external codes or test data. |
| |
Added
a parameter for identifying real values in output
set lists:
Added PARAM, OUTSETTOL which specifies
the tolerance for identifying real values in
output set lists. A real value is considered
as included in a set if the ratio of the difference
between the set value and input value or the
input value is less than OUTSETTOL. |
| |
Added
EXCLUDE and INCLUDE options to the MODESET Case
Control command:
Primarily for use in DDAM analysis,
but with applications in all response analysis,
this feature allows a user to quickly isolate
a few important modes from a large number of
modes and test the response. Combined with the
Modal Database restart feature, it becomes a
fast and powerful investigation tool. Added
an EXCLUDE option to the MODESET Case Control
command. EXCLUDE allows the specification of
a SET of modes that are to be excluded from
the extracted set. Also, added an INCLUDE option
which is functionally the same as SET. |
| |
Added
support for multiple MODESET Case Control commands:
MODESET now allows the use of multiple
options to include and exclude modes. This productivity
improvement allows great versatility in choosing
target modes to investigate in modal response
solutions. |
| |
Modified
a parameter which will disable frequency response
neutral file vector for random response solutions:
Modified PARAM, FREQRESPRSLTOUT which
now when set to OFF will disable frequency response
neutral file vector and element output for random
response solutions. Previously only element
output was disabled. This represents a significant
improvement in performance for cases where the
frequency response data is not needed, only
the PSD, RMS and NPX data. This is typical in
practice where the user has already validated
the frequency response analysis and is now carrying
out the random response analysis. |
| |
Modified
a parameter which will disable random response
PSD neutral file vector for random response
solutions:
Modified PARAM, RANDRESPRSLTOUT which
now when set to OFF will disable random response
PSD neutral file vector and element output for
random response solutions. Previously only element
output was disabled. This represents a significant
improvement in performance for cases where the
PSD response for each DOF is not required for
X-Y plotting, but contour mapping of RMS and
NPX data is required. This is typical in practice
where the user has already validated PSD response
at key degrees of freedom and now wants to assess
the complete structure response. |
| |
Added
a directive for enabling DMIG support for the
PCGLSS solver and LANCZOS eigensolver:
Added the PCGLSSDMI directive which
when set to ON enables DMIG support for the
PCGLSS solver and LANCZOS eigensolver. |
| |
Added
multi-phase DDAM operation capability:
A multi-phase DDAM operation capability
has been added to improve productivity in a
mixed secured and unsecured environment. The
integrity of the DDAM coefficients is essential
and this feature preserves this, while allowing
the user more flexibility. A new parameter controls
which phase of a DDAM analysis is to be run.
This allows an initial (phase 1) DDAM checkout
run to be carried out in an unsecured environment;
the run can then be restarted in a secure environment
using the Modal database (phase 2). A new DDAM
database has been created which allows storage
of the shock input G versus frequency spectra
calculated from the DDAM coefficients. This
is the only file, which needs to be exported
from the secure environment, and is easily verifiable
for content. The final phase 3 is then to calculate
the DDAM responses in the unsecured environment. |
| |
Modified
DDAM response calculation:
Modified response calculation to include
an additional requirement that all modes above
1 percent modal effective mass are included.
Prior to this it was possible, but very unlikely,
that the 80 percent modal effective mass cutoff
would exclude a mode with greater than a 1 percent
contribution. |
| |
Modified
the method used for DDAM displacement, velocity,
acceleration, and single point constraint vector
results calculations:
The previous method performed an NRL
summation using as the maximum response mode,
the entire modal vector having the largest response
based on modal participation factor scaling.
The new method looks at each degree of freedom
to determine the maximum response mode and uses
that value as the maximum for the NRL summation.
This is a more conservative approach with strict
compliance with NAVSEA 3010. The stress responses
are calculated independently and have not changed. |
| |
Enhanced
DDAM von Mises output stress in bars, beams
and shells:
As requested by the DDAM community,
a new model parameter, EQVSTRESSTYPE now controls
the von Mises stress calculation. When set to
2 in linear solutions this will output membrane
only von Mises stress in bar, beam, and shell
elements. The default setting of 0 will output
membrane and bending von Mises stress. The beam
and bar von Mises calculation has been completely
updated to include both transverse shear terms
and the torsional shear stress term. The effective
section shear area is used to calculate the
former. The latter uses either a user supplied
effective torsional radius, or the appropriate
dimension if the user inputs a section via a
PBEAML or PBARL. |
| |
|
|
| Composite
Analysis Enhancements |
| |
Added
2D orthotropic material (MAT8) support
for composite solid elements:
PCOMP entries associated with
layered solid elements can now automatically
convert the 2D properties on MAT8 entries
to the 3D MAT12 format. This provides
a very easy migration path for users
with legacy 2D orthotropic shell models,
or data, wishing to transition to the
new 3D solid composite elements. |
 |
|
| |
Added
failure plane angle output for LaRC02 failure
criteria:
Added failure plane angle (alpha) output
for LaRC02 failure criteria. |
| |
Added
plain strain support for orthotropic shell elements:
Added plain strain support for orthotropic
shell elements via the MAT8 Bulk data entry.
This is a popular method for very large, stiff
joint cross sections in the maritime industry.
It allows for approximation of the appropriate
directional material properties in a plane strain
orientation. |
| |
Added
a parameter to specify the maximum number of
iterations used in determining composite LaRC02
strength ratios:
Added PARAM, MAXSRITER which is used
to specify the maximum number of iterations
used in determining composite LaRC02 strength
ratios. |
| |
Enhanced
composite transverse shear stress:
Enhanced composite transverse shear
stress for plies with orientation angles other
than zero or 90 degrees and unsymmetric lay-ups.
The new method gives a slightly more accurate
result. |
| |
|
|
| |
New
formulation for CTRIA3 and CTRIAR element bending
stiffness:
Added a new element bending stiffness
formulation (DKT) which gives more accurate
solutions for coarser mesh densities. The new
formulation is set as the default and is controlled
using the TRIELEMTYPE model parameter. The previous
element formulation can be selected by setting
PARAM, TRIELEMTYPE to SRI. The DKT option is
available in all solutions. |
| |
New
formulation for CQUAD4 and CQUADR element bending
stiffness:
Added a new element bending stiffness
formulations (DKQ and DKT) which may give more
accurate solutions for coarser mesh densities.
The new formulation is controlled using the
QUADELEMTYPE model parameter. Generally, the
SRI option is more accurate but in cases with
large length to thickness ratios, the DKQ and
DKT options may provide better results. The
DKQ option is supported in all solutions. The
DKT option is supported in all linear solutions. |
| |
Added
support for general elements:
Added support for general elements
via the GENEL Bulk Data entry. |
| |
|
|
| |
Added
results neutral file compression:
Added results neutral file compression
via the RSLTFILECOMP directive for grid point
vector and element load files. When RSLTFILECOMP
is set to ON or AUTO and ON is selected by the
program, disk space requirements for intermediate
results neutral files are significantly reduced
and in most cases performance is increased especially
for models with composite properties and SUBCOM
Case Control commands. |
| |
Added
a parameter to output normalized stress error
measures at each grid:
Added PARAM, STRESSERROR which when
set to ON will output normalized stress error
measures at each grid and a relative solution
error for all shell and solid elements by surface
and volume respectively. This is a very useful
feature as it provides a graphical assessment
of mesh quality allowing easy identification
of areas requiring mesh refinement. |
| |
Added
support for extended results labels:
Added support for extended results
titles and labels in the FEMAP Binary Results
File (.FNO). The new labels are now up to 80
characters long and provide a better description
of the associated results measure. |
| |
Added
support for real-time element X-Y plotting and
.CSV file generation:
Added element data support for XYDATA
and XYDATAGEN Case Control commands. .CSV file
support is also added. This enhancement and
the previous nodal data output enhancement mean
that the user who wants limited response data
quickly, or who wishes to use response data
in his own or third party programs can avoid
the need to parse the Model Results Output File.
Previous MSC or NX users in particular will
find great utility in avoiding the need for
parsing the F06 file. |
| |
Additional
output for bars and beams:
Added von Mises stress output for bar
and beam elements. The beam and bar von Mises
calculation has been completely updated to include
both transverse shear terms and the torsional
shear stress term. The effective section shear
area is used to calculate the former. The latter
uses either a user supplied effective torsional
radius, or the appropriate dimension if the
user inputs a section via a PBEAML or PBARL. |
| |
Additional
support in linear solution for output stress
in bars, beams and shells:
Added PARAM, EQVSTRESSTYPE which when
set to 2 in linear solutions will output membrane
only von Mises stress in bar, beam, and shell
elements. The default setting of 0 will output
equivalent stress for material nonlinear solutions
and von Mises stress for all others. |
| |
Support
for translating the global applied load vector
into FORCE and MOMENT Bulk data entries:
Added the TRSLDISPDATA directive which
when set to ON will translate the global displacement
vector into SPC Bulk Data entries. The OUTDISPSETID
directive is used to specify the output set
id. |
| |
Added
support for translating the global displacement
vector into SPC Bulk Data entries:
Added the TRSLDISPDATA directive which
when set to ON will translate the global displacement
vector into SPC Bulk Data entries. The OUTDISPSETID
directive is used to specify the output set
id. |
| |
Added
a parameter for the method used in grid point
force balance calculations:
Added PARAM, GPFORCEMETHOD which specifies
how grid point forces are calculated. The NORAN
option uses the previous method which only calculates
element force contributions for elements which
have an element FORCE request. The NASTRAN option
considers all elements regardless of FORCE request
and is consistent with MSC and NX Nastran. |
| |
Provided
support for MSC Nastran element type codes and
labels compatibility:
Added the PCHFILETYPE directive which
when set to NASTRAN will provide compatibility
with MSC Nastran element type codes and labels. |
| |
Enhanced
DMI strain data:
Increased precision of exported strain
and direct matrix import (DMI) data. |
| |
New
output results for static and prestress static
solutions:
Added multipoint constraint vector
resultant output to linear static and prestress
static solution sequences. |
| |
Added
new output vector to the Model Results Output
File:
Added rigid body acceleration vector
output to the Model Results Output File when
PARAM, INREL is set to ON or -1. |
| |
Added
support for specific strain output:
Added support for specific strain output
via the THERMAL, MECH, and TOTAL options on
the STRAIN, ELSTRAIN, and GPSTRAIN Case Control
commands. The THERMAL option will output thermal
strain and the MECH option will output mechanical
strain in place of the default TOTAL strain. |
| |
Enhanced
Model Result Output File:
Reduced Model Result Output File size. |
| |
Added
results support for CADAS:
Added results neutral file support
for the CADAS pre- and post-processor via the
RSLTFILETYPE directive and CADAS setting. |
| |
Added
a parameter for specification of units for output
results:
Added PARAM, UNITS which allows the
specification of the units used in the model
for output labeling and report generation. |
| |
|
|
| |
Added
better temperature dependent material support:
Added support for temperature dependent
density in linear static solutions with more
than one subcase. Previously, the temperature
dependent density from the first subcase was
used for all subcases. |
| |
Added
support for heat flux interpolation:
Added support for heat flux interpolation
via the QBDYG Bulk Data entry. |
| |
Modified
how neutral files are deleted at initialization:
Modified how the PURGE directive handles
deletion of results neutral files on initialization.
Previously, all neutral files were deleted regardless
of if they were requested. Now only the neutral
file type requested will be deleted. |
| |
Added
new options for LOADINTERPOLATE command:
Added two new options for the LOADINTERPOLATE
Case Control command: SFORCE and PNORMAL. SFORCE
is similar to the FORCE option except that the
output total force is scaled to equal the input
total force. PNORMAL is similar to the PRESSURE
option except the pressure is forced to be normal
to the element surface. |
| |
Added
support for translating element pressure loads
into PLOADG Bulk Data entries:
Added the TRSLPRESDATA directive which
when set to ON will translate element pressure
loads into PLOADG Bulk Data entries. The OUTGRIDOFFSET
directive is used to specify the starting grid
point id associated with the generated PLOADG
entry. This enhancement improves the bidirectionality
of data mapping between NEiNastran and external
CFD programs or other applications requiring
point wise definition of pressure. |
| |
Enhanced
translation of heat transfer models:
Improved translation performance for
heat transfer models with CONV Bulk Data entries. |
| |
Enhanced
superelement analysis:
Added support for user defined single
point constraints on superelement interior grid
points. |
| |
Added
information to the .LOG file:
Added parameter and directives settings
information to the .LOG file. |
| |
Added
a directive for providing timing information
to the .LOG file:
Added ELAPSEDTIME directive for providing
detailed timing information to the .LOG file. |
| |
Added
heat transfer solution support for LOAD Bulk
Data entry:
Added support for load combination
via the LOAD Bulk Data entry in heat transfer
solutions for heat flux loads (QBDY1 and QBDY2
Bulk Data entries) and volumetric heat addition
loads (QVOL Bulk Data entries). |
| |
Enhanced
model initialization directives:
Added single directive support for
FILESPEC, FILEBUFFERSIZE, FILEPFACTOR, and NFILEBUFFER. |
| |
Enhanced
Bulk Data processing:
The following enhancements related
to bulk Data processing were made:
| •
|
Added
support for mixed lower and upper case
for ENDDATA, PARAM, and INCLUDE Bulk
Data entries and BEGIN BULK Case Control
command. |
| •
|
Added
wide field support for PLOADG Bulk Data
entries. |
| •
|
Changed
the handling of repeated SPC requests
where both zero and non-zero SPC Bulk
Data entries are specified at the same
degree of freedom so that now a non-zero
SPC will not be overwritten by a zero
value at the same degree of freedom. |
| •
|
Added
SEID field support to the GRDSET Bulk
Data entry. |
| •
|
Changed
default behavior for PLOAD4 Bulk Data
entries when a zero magnitude orientation
vector was defined so that now the pressure
will be oriented normal to the surface
(default). |
| |
|
|
|
The
NEiNastran Editor has been updated with new
features, such as:
| •
|
Editor
Graphical User Interface modified to
enhance user interface usability. |

Added
the capability to delete all plots and
to delete individual plots. |
| •
|
Added
visualization and display of results
for rigid body elements. |
| •
|
Added
markers for maximum and minimum values
on contour plots, which can be toggled
on or off using graphics view popup
menu. |
| •
|
Added
the "TOTAL" calculated results, such
as “TOTAL ROTATION” and
