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 model are proposed for simulations with the seat model as well.
In case modifications in the control cards are needed for the seat model, we offer to run a subset of the validation runs with the modified control cards to evaluate the influence. Please contact your local support for details.
All nodes have a connection to an element except the third beam nodes of all beam elements.
The model is free of initial penetrations
The Version 4.0.1 of the BioRID provides parameters to scale the joint friction 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. The scale factors are used for the left and right hand side assemblies. So it is not possible to scale left and right assembly differently.

One more additional parameter has been defined in the model. It is used to switch off the dynamic relaxation of the model. swrelax=1 means on and swrelax=0 means off.
The validation of the model has been done based on all tests which are shown in the manual. Goal of the validation process is to get a model with physical definitions as close as possible to the test results. It might be possible that there are loading conditions which are not observed until now in the validations test and the validation does not fit to these new unknown conditions. Due to this the user is responsible for his own results.
