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
