Reply To: A simple compression problem of an elastic structure

Dear Peter, 

Thank you for your valuable advices.

I made some improvements by adjusting fitting model, but still it did not converge completely. Inserting Keyopt,matid,6,1 using Command object seems to be not effective for this case.

Here are some results, and N-R Force residual. Still max point of N-R force residual was inside the elastic structure.

I used tetragonal mesh, with its contact matched to both plates.

What would be effective for this simulation to converge more?
