New version of LS-DYNA is released for all common platforms.
The release provides fixes and extensions.
Features and enhancements included in V971 R3.2.1 that were not available in V971 R3.2 include the following:
Elements:
Added 1-way slipring
Add sliprings’ fs and fd as function of time when <0
Loads:
Added option *LOAD_SEGMENT_SET_ANGLE
Add warning in *LOAD_BLAST when segments are too close and empirical equation may no longer be valid
Output:
MESSAG:
Changed the restart name from messag to message#
D3PLOT:
Added flag to d3plot database to signal LsPREPOST that 4 inplane integration points are output. For 1 point shells 3 null inplane points are output.
The remainder of this release notes describes many other enhancements, additions, and fixes made since the release of LS-DYNA version V971 R3.2.
General
Fix selective mass scaling bug related to element sorting
Fix in MPP for certain SPC condition non properly enforced in ALE constrain and penalty coupling
Boundary Condition
Fix in MPP for certain SPC condition non properly enforced in ALE constrain and penalty coupling
Fix in temperature boundary condition nodes due to noise from interpolation
Constrained Options
Fix initialization of *CONSTRAINED_INTERPOLATION for solid only models.
Contact Options
Fix for a possible segmentation fault with eroding segment based contact
Fix in MPP for initialization problems of some slave node arrays in *CONTACT_ERODING_NODES_TO_SURFACE
Fix for THKOPT=2 on Contact Optional Card B is working again
Fix in MPP for MPP Tied Contact
Control Options
Fix memory problem with *CONTROL_SHELL, ESORT=2 when the model contains any *SECTION_SHELL, ELFORM=5 or *MAT_034 (*MAT_FABRIC)
Fix selective mass scaling bug related to element sorting
Fix in MPP for *CONTROL_MPP_DECOMPOSITION_PARTS_DISTRIBUTE and new keyword *CONTROL_MPP_DECOMPOSITION_PARTSET_DISTRIBUTE
Fix for IACOOP=2 filtering. Filter initial conditions were not stored properly, thus affecting accuracy of results
Database/Output
Fix missing legend in MPP version of matsum file
Fix in MPP for drdisp.sif file output
Fix for restart ascii files that were missing for any restart run
Fix for output formats of belt curves and retractor number
Fix for error message for *ELEMENT_BEAM_SECTION
Fix for hex weld assemblies so that those generated by *DEFINE_HEX_SPOTWELD_ASSEMBLY go through the assembly failure routine and output to swforc as an assembly instead of individual elements
Define options
Fix for *MAT_083 with *DEFINE_TABLE and *INCLUDE_TRANSFORM. Strain rates are in Table abscissa are now transformed correctly
Fixed hex spot weld assemblies that under certain circumstances were failing at the wrong time.
Fix for memory handling of *DEFINE_FUNCTION
Fix for hex weld assemblies so that those generated by *DEFINE_HEX_SPOTWELD_ASSEMBLY go through the assembly failure routine and output to swforc as an assembly instead of individual elements
Fix for adaptivity when *DEFINE_FUNCTION is used
Elements
Fixes for user defined solid
Fix for *ELEMENT_SEATBELT_SENSOR, which now behaves consistently with the User’s Manual
Fix for output formats of belt curves and retractor number
Fix for error message for *ELEMENT_BEAM_SECTION
Fix in slipring definition which happens when more than one slipring is defined in one single *ELEMENT_SEATBELT_SLIPRING
Include Options
Fix for *MAT_083 with *DEFINE_TABLE and *INCLUDE_TRANSFORM. Strain rates are in Table abscissa are now transformed correctly
Fix for *MAT_034 (*MAT_FABRIC) and include transformation of FAC load curve
Material Models
Fix for Green Naghdi stress rate problem for *MAT_035
Fix in keyword reader for *MAT_165. *MAT_COMPOSITE_MSC_DMG now can be read as well as *MAT_COMPOSITE_DMG_MSC or *MAT_162.
Fix for FPE in load curve lookup for *MAT_187 (SAMP-1)
Fix for *MAT_090 (*MAT_ACOUSTIC) with SMP consistency flag on
Fix for *MAT_083 with *DEFINE_TABLE and *INCLUDE_TRANSFORM. Strain rates are in Table abscissa are now transformed correctly
Fixed hex spot weld assemblies that under certain circumstances were failing at the wrong time.
Fix memory problem with *CONTROL_SHELL, ESORT=2 when the model contains any *SECTION_SHELL, ELFORM=5 or *MAT_034 (*MAT_FABRIC)
Fix for *MAT_036 related to out-of-plane shear stress cap
Fixes for *MAT_187. Time step calculation now also correct in case BULK and GMOD are not given
Fix for *MAT_034 (*MAT_FABRIC) and include transformation of FAC load curve
Fix for hex weld assemblies so that those generated by *DEFINE_HEX_SPOTWELD_ASSEMBLY go through the assembly failure routine and output to swforc as an assembly instead of individual elements
Fix for *MAT_162 causing improper delamination behavior in elements without a neighbor element
Section Options
Fix memory problem with *CONTROL_SHELL, ESORT=2 when the model contains any *SECTION_SHELL, ELFORM=5 or *MAT_034 (*MAT_FABRIC)
Termination
Fix for adaptivity when *TERMINATION_CURVE is used
