hello
I'm modeling two solids: an hard contact exists between the two solids so that there is no penetration of one solid in the other. Then I want to constraint a part of the common surface with a MPC function in order to link the two solids.
An error message occurs : because of the MPC...
I'm doing a plastic analysis ( perfect plasticity ) and I get this warning before the analysis stops

When I'm performing a static analysis, one element differs from the others in the result (big discontinuity in the stress field). Any idea where it can come from?
Thanx

I'm trying to remove boundary conditions in the last step of a steady state analysis.
The problem is that the reaction forces are too important and removing the boundary conditions implies a too big movement of one of my parts.
-> Fixed time increment is too large
What should I do...
Hello
I'm tying to get the residual stress in a welded structure. I'm making a sequentially coupled thermal stress analysis: I use the temperature history of the heat transfert analysis as a predefined field in the stress analysis. I have exaclty the same mesh in the two analysis.
I get a...
