I was solving the side car crash problem in hyperworks 2021 version. I have correctly applied the BC's in hypercrash. But in the post-processing I am not getting desired Output, because the car model crossover through the cylindrical pole. I don,t know what I have done wrong. Please guide me to solve this problem.

In post-processing I am getting this type of output.(below link)

Radioss file 0000.rad is attached in below link.

    Thanks for your Reply, 

    I am using the /INTER/TYPE7 for contact with /RWALL , so what should I do next to make it correct. Please check the Attachment

    For the interaction of your structure nodes  with /RWALL you do not need to define  /INTER/TYPE7.

    What you need do stablish is the nodes that will have interaction with the rigid wall setting  either "grnod_id1" or the distance to the wall 'dsearch', within the /RWALL card.

     

    I hope this is helpful

    Hi

    Be sure you do not have incompatible kinematic conditions like secondary nodes of /INTER/TYPE2 set to interact with the /RWALL.

    In this case set Spotflag=27 or 28 in the contact, so that they are not removed from the interaction to the /RWAL

     

    I Hope this is helpful

    Regards
