LS-DYNA Interface

New Features

Support for LS-DYNA F14.1 and R15.0 Profiles
Support for LS-DYNA F14.1 and R15.0 profiles has been added.
New Mass Balance Workflow
The Mass Balance tool can be used to automatically distribute masses on nodes or properties, to match user-defined target mass and CoG of selected properties.

Enhancements

Find Attached Tool
*CONSTRAINED_EXTRA_NODES_{OPTION} and *CONSTRAINED_RIGID_BODIES are considered in find attached tool via check boxes in the tool options.
Model Checker
A new “*CONSTRAINED_INTERPOLATION with weight factors equal to 0.0” warning has been added.
Keywords Support
Support of *CONTROL_FORMING_ONESTEP_{OPTION} has been added.
Support of new material *MAT_DMN_COMPOSITE_FRC has been added.
Support of *LOAD_NODE_SET_ONCE has been added.
*MAT_PIECEWISE_LINEAR_PLASTICITY:
  • All the material options (2D, LOG_INTERPOLATION, STOCHASTIC, MIDFAIL, TITLE) are activated by a check box to allow any combinations of those options in the material keyword.
Support of attribute DSID in *ELEMENT_SEATBELT_RETRACTOR from R12 profile has been added.
Support of attribute THERML in *MAT_HYPERELASTIC_RUBBER from R8 profile has been added.
The following keywords have been updated based on R14 solver manual:
  • *LOAD_BEAM
  • *MAT_ELASTIC_VISCOPLASTIC_THERMAL
  • *MAT_HYSTERETIC_SOIL
  • *MAT_BOLT_BEAM
  • *MAT_COHESIVE_GASKET
  • *MAT_REINFORCED_THERMOPLASTIC
  • *MAT_ENHANCED_COMPOSITE_DAMAGE
  • *MAT_OGDEN_RUBBER
  • *MAT_JOHNSON_HOLMQUIST
  • *MAT_GLASS
  • *MAT_SPRING_GENERAL_NONLINEAR

Resolved Issues

  • Performing nodes equivalencing workflow will now maintain ELEMENT_MASS defined on equivalenced nodes.
  • Default weighting factors in *CONSTRAINED_INTERPOLATION are now defined equal to TWGHTX value and not more equal to 0.0.
  • The review of *CONTACT_AUTOMATIC_SINGLE_SURFACE with SSID=0 has been fixed.
  • *CONTACT_AUTOMATIC_SINGLE_SURFACE with SSID=0 is no longer found as empty in check tools.
  • *SET with option COLLECT is now correctly combined when include files are imported successively in HyperMesh.
  • The option OFFSET in *ELEMENT_BEAM is now accessible from the element Entity Editor.
  • The model import issue when encryption block is defined after *MAT_SEATBELT has been fixed.
  • The import of *SECTION_SOLID_EFG when attributes IEBT=0 or IDIM=0 or IBR=0 has been fixed.
  • NUM attribute in *MAT_154 is now supported as an integer.
