This file constitutes revision 0 of the release notes for LS-DYNA version R9.2.0.
———————————————————————————<\/p>
version R9.2.0. Please contact your LS-DYNA distributor (keys@lstc.com if
you’re a direct customer of LSTC) if you need to have your license updated.<\/p>
There are few instances mentioned below in which the R10.0 User’s Manual
should be consulted.
Both Manuals are available at www.lstc.com\/download\/manuals .<\/p>
since the release of version 9.1.0. The changes are primarily just bug fixes.<\/p>

in MPP, when excessive mass exchange is yielded due to numerical noise.<\/p>
– CPM now supports leakage parameter from *MAT_ADD_AIRBAG_POROSITY_LEAKAGE.
– Change dm_out calculation to better treat trunction error.
– Fix bug affecting *AIRBAG_CPM_INTERACTION if the slave bag has chamber definition.
The downstream pressure should use the slave chamber pressure for evaluating the
venting from the master bag.<\/p>
*BOUNDARY_PRESCRIBED_MOTION_RIGID while rotational DOF are constrained on Card 2 of *MAT_RIGID.<\/p>
used as a CESE boundary condition. This was likely an issue only if more
than one blast was simultaneously in use.<\/p>
blasts available as boundary conditions in *LOAD_BLAST_ENHANCED.<\/p>
and later versions. This also works for d3plot output with the 2D CESE
axisymmetric solver.<\/p>
Schlieren number and the chemical species mass fractions.<\/p>
– using *ELEMENT_SHELL_SHL4_TO_SHL8, or
– using a large part id like 100000001.<\/p>
ncpu<0. Applies to SMP only.<\/p>
instead of tabulated input cards.<\/p>
It was previously hardcoded to 1.01.<\/p>
were being changed. This problem existed in R9.1.0 but not in prior releases.<\/p>
has no segments.<\/p>
contact with DEPTH=5. The consequence was to sometimes choose the wrong part when
looking up the scale factor so the stiffness was not predictable.<\/p>
SOFT=2 contact. It was possible that segments passed from one processor to
another for contact checking would have a zero stiffness and would therefore penetrate.<\/p>
contact option with SOFT=2 contact, because that option is not available.
The contact type is switched to SOFT=1.<\/p>
node sets to define the contact surfaces. The master side was likely to trigger
an erroneous error about missing nodes, which terminated the job.<\/p>
yield stress data of *MAT_TABULATED_JOHNSON_COOK\/*MAT_224 provided as input in
subroutine usrfrc.<\/p>
Compressive contact forces were erroneously “damaged” as well.<\/p>
contact of the beam nodes from both sides of the contact surfaces.<\/p>
now support the SPOTDEL option of *CONTROL_CONTACT. That means if shell
elements involved in the SPR domain fail, the SPR gets deactivated.<\/p>
Beam type 9 (spotweld beam) and thick shells are supported for selective mass scaling.<\/p>
*ELEMENT_SOLID_TET4TOTET10.<\/p>
error when using *NODE_THICKNESS_SET with *SET_NODE_INTERSECT.<\/p>
on *CONTROL_SHELL and there are triangular elements in the mesh.
Triangular elements were being deleted immediately by the distorted element check.<\/p>
error terminations. This does not affect results, but allows models to run.
SOL+865 is an error that occurs if a discrete element has zero translational mass.
SOL+866 is an error message that occurs when a discrete element has zero rotational mass.<\/p>
double precision for local coordinates and other internal variables.<\/p>
This hopefully resolves rarely occuring instability issues.
Option ICOH on *CONTROL_SOLID is used for that; see R10 manual for details.<\/p>
Inconsistent results were possible since version R9.0.<\/p>
(*SECTION_SOLID, ELFORM=13), e.g., correctly handle initial volumes
from *INITIAL_STRESS_SOLID, use double precision for some internal variables.<\/p>
Bug fix for duplicate nodes generated for blank edge to gage pin contact.<\/p>
Remove an extra blank line output in *ELEMENT_SHELL_THICKNESS.<\/p>
Fix excessive INTFOR file output.<\/p>
Fix for running acoustic analysis with multiple b.c. in MPP.<\/p>
– Fixed bug in running SSD fatigue in MPP.
– Fixed a bug in running interpolation on load curve when there is only one
frequency in the load curve.
– Fixed a bug in running FREQUENCY_DOMAIN_SSD with hex20.
case from Hitachi. same as r114711 in trunk version.<\/p>
– Added missing arguments.
– Fixed a bug in extracting modal stress for response spectrum analysis.
– Added von mises stress output for beams.<\/p>
– Fixed a bug in running FEM acoustics with existing exterior structures.
– Minor fix for writing eigout_ac, with case id.<\/p>
– one more fix for reading FRF keyword.
– Minor fix for reading FRF keywords.<\/p>
Fixed a bug in accessing eigenmode databases, when *FREQUENCY_DOMAIN_PATH is defined.<\/p>
Fix a problem marking the end of the d3eigv file when modal stresses are written.<\/p>
relaxation contrary to the manual. Such times are now ignored with dynamic
relaxation.<\/p>
problem to match that of rotational dynamics.<\/p>
implicit.<\/p>
processes. A future enhancement is to allowed a part in *PART_MODES to be
split across processes.<\/p>
implicit keywords with the _SPR option were not properly handled. Now such
keywords are properly handled.<\/p>
implicit follows explicit dynamic relaxation.<\/p>
Fix a problem when using 4- or 6-noded solids, or 3-noded shells in rotational dynamics analysis.<\/p>
and rotational velocity OMEGA is not zero and *PART_INERTIA is also present.<\/p>
which were using the wrong offset<\/p>
warping stiffness (BWC=2 on *CONTROL_SHELL), and when OSU=1 on *CONTROL_ACCURACY
to activate an objective stress update. Prior to the fix, there was no thermal
loading available for this combination of options.<\/p>
with FAIL>0.0 and IACC=1 in *CONTROL_ACCURACY.<\/p>
*MAT_TABULATED_JOHNSON_COOK\/MAT_224 and *MAT_TABULATED_JOHNSON_COOK_GYS\/MAT_224_GYS.<\/p>
mixed quad and triangular elements in the fabric part:
– when a reference geomeotry is used, a flaw in the strain calculation was leading to
possible NaN forces in the elements, and
– when a reference geometry is not used, the forces from triangular elements in
mixed element blocks were 2 times too high.<\/p>
This will most probably have no effect to any real application, but could be seen
in very special 1-element tests.<\/p>
for GAB and only providing stress-strain-curves for positive shear.<\/p>
table definition for EA, EB or GAB under compressive loading.<\/p>
New parameter FTSCL on Card 2, field 8, is an optional scale factor
for the tensile strength: FT_mod = FTSCL * FT. As soon as first crack
happens in a part, tensile strength drops to its original value, FT.<\/p>
Tensile behavior under 45 degree to the material direction was incorrect.<\/p>
for use in R9.2.0; see R10 manual for details of this material.<\/p>
e.g. current yield stress (5) and triaxiality (7); see R10 manual for details.
This affects only the output.<\/p>
been low since version R9.0.<\/p>
New parameter MIDFAIL=1 (Card 4, field 8) activates a procedure, where
critical strain is only checked at the mid-plane integration point(s),
i.e. an odd number for NIP should be used. The other integration points
compute their damage, but no coupling to the stresses is done.
As soon as the mid-plane IP reaches ECRIT\/DCRIT, all the other IPs are now
also checked. Those of them that are already “above” their critical value
immediately start to reduce the stresses. Those who are still “below” critical
still do not couple, only if they reach their criterion.<\/p>
Could only happen sometimes if ECRIT=0 and DCRIT=1.<\/p>
to *MAT_ADD_GENERALIZED_DAMAGE; see R10 manual for details.<\/p>
IFLG1 = “flag 1” (0 or 1 or 2) + 10 * “history variable slot”.<\/p>
Failure function limit for OPT = 0 or -1, and DMGOPT = 10, 11, or 12.
See R10 manual for details.<\/p>
with logarithmic strain rate table.<\/p>
Results could have changed between R7 and R8.<\/p>
Sometimes temperature dependent yield curves (LCKT) were not used correctly.<\/p>
Convergence speed could have been low in versions R9.0 and R9.1.<\/p>
were not eroded even if enough integration points reached their failure criterion.<\/p>
The extended Barlat model is implemented, where r00\/r45\/r90\/shear\/biaxial hardening
and r-values can be specified independently to render more accurate results. Also,
hardening flag 7 in the regular Barlat model (*MAT_036\/*MAT_3-PARAMETER_BARLAT) is
restored to behave as it did in earlier versions.<\/p>
during MPP decomposition.<\/p>
The error could occur when SOFT=2 contact is used with the periodic intersection
check and process 0 does not participate in the contact.<\/p>
and *MAT_ADD_EROSION with IDAM.ne.0 (GISSMO or DIEM).<\/p>
is set and INTSTRN=1 in *INTERFACE_SPRINGBACK.<\/p>
FATXML is an open, standardized data format based on
the Extensible Markup Language (XML) which is developed by the German Research
Association of Automotive Technology (Forschungsvereinigung Automobiltechnik – FAT).
It is designed for consistent data management in the overall CAE process chain.<\/p>
The TITLE in *SECTION_*_TITLE was not written correctly to d3prop.<\/p>
*INITIAL_VELOCITY_GENERATION and *CHANGE_VELOCITY_GENERATION are in
the input file.<\/p>
restart will not be set less that stored value, thereby avoiding a possible
segmentation fault.<\/p>
Corrected SMP contact force output into rcforc ASCII file for the case with
multiple definitions of *CONTACT_2D_NODE_TO_SOLID keyword in the input file.<\/p>
*SET_NODE_ADD that occurs in input before the sets it references.<\/p>
*SET_SEGMENT_GENERAL to delete segments.<\/p>
And make that check equivalent in single and double precision.<\/p>
gmbin file is read in correctly in MPP.<\/p>
– A new command line option is added to load one module file without changing the
input deck, as “module=filename”. It provides back compatibility to the input
without the *MODULE keywords.
– The system paths defined in LD_LIBRARY_PATH are also included for searching module
files for those filenames starting with “+”.<\/p>
