LS-DYNA V971 R3.2.1 (R3.47756)
Release notes for LS- DYNA version ls971.R3.2.1 (R3.47756) and mpp971.R3.2.1 (R3.47756)
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
ALE
- 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
