Am doing compression analysis using rwall to compress a tetrahedran mesh solid to get force vs stroke but the grapgh is having many dips than a smooth stabilized curve, for each element deletion the force is coming down how can i make the force vs st

    Hi

    If you are using /RWALL I understand you are using constant imposed velocity (this is the case when Mass=0)

    In this scenario I think that when material is removed by deletion, the wall will still keep same velocity but reaction force will reduce.

    Due to that, I would expect dips in the reaction force.

     

    I hope this is helpful

    Regards

    Hello Rogerio

    You are right am using imposed velocity for Rwall. Is there any options to avoid the reaction force dips to stabilize or to make it smooth curve. I mean any options on contact or material prop or anything
