Contact Problem
Contact Problem
(OP)
I'm trying to model the clash between a rigid body and a deformable one, but the rigid body actually penetrates fully in the deformable causing the stress values to go to wcompletely wrong values. Can anyone give me an idea, how to simulate a contact between any impactor ( rigid body ) and a deformable body ?





RE: Contact Problem
- You need to set NLGEOM on in the *STEP card if you want to see any geometric non-linearities.
- Both bodies are meshed with deformable brick elements. You would be better looking at using either analytical rigid surfaces, or rigid elements. I susopect that you may have to use rigid elements for this case.
