Hi all,
I have problem after my explicit simulation finishes. It is a quasi static simulation and in the second step I have ALLKE << ALLIE
I use mass scaling to reduce the calculation time
At the end, on one part, the stress I get is very noisy and discontinuous. I tried to refine the mesh but the problem stays the same. I think of an incompatibility in my model but I don't know what.
On the part I am showing, I have a contact with a membrane at some part of the calculation. The contact is well established. The part is subjected to internal pressure.
If I plot the Von Mises discontinuity field, it is obvious that something is wrong
If anybody has an idea of what causes this noise the idea is welcome.
Thanks
