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

• If the keyword *CONTROL_MPP_DECOMPOSITION_ARRANGE_PARTS is erased from the model, the simulation time in large models could be 2-3 times longer. It is strongly recommended to use this control card in MPP simulations.

 

• The model should be used with a time step size of 0.7 microseconds or less!

• If a model for right side impact is needed, please contact DYNAmore. RHD models in both systems of units are available.

 

• All nodes are connected to an element, except the third beam nodes of the beam elements.

 

• No massless nodes are present in the input file of the dummy, except the third beam nodes of the beam elements.

 

• The model is free of initial penetrations.

 

• The Version 4.0 and higher of the WorldSID provides parameters to scale the friction of the joint for all limbs. As default a 1 g adjustment of the joints is included. The user is now able to increase or decrease the friction values of the joints. A common scale factor is used for the left and right hand side assemblies. So it is not possible to scale left and right assembly differently.
