Additional Remarks

  • The modification of the *CONTROL cards of the dummy file may have an influence on the performance and robustness of the model. Therefore the *CONTROL cards of the dummy models are proposed for integrated simulations as well.

      Important flags on LS-DYNA control cards:

      *CONTROL_ACCURACY flag INN=2

      *CONTROL_BULK_VISCOSITY flag TYPE=-1

      *CONTROL_SHELL flag ESORT=1

      *CONTROL_SOLID flag ESORT=1

      *CONTROL_MPP_DECOMPOSITION_ARRANGE_PARTS

      *CONTROL_CONTACT flag FTALL=1 (for X-RAI)

  • If the CONTROL_MPP_DECOMPOSITION_ARRANGE_PARTS is erased from the model the simulation time in large models can be two or three times longer. It is strongly recommended to use this control card in MPP simulations.
  • The model should be used with a timestep of 0.9 microsecond or less!
  • If a model for right side impact is needed, please contact DYNAmore. RHD models in both system of units are available.
  • All nodes are connected to an element.
  • There are no massless nodes in the input files of the dummy.
  • The model is free of initial penetrations.
