Hello, I have made a model using contact, CCX. When I solve the model the deformed view shows the elements crossing each other. I have tried refining the mesh and swapping the master/slave parts relationship. I have also tried increasing and decreasing the the "slope of pressure-overclosure curve K" an order of magnitude. I haven't been able to stop the elements from overlapping (model attached). Any suggestions as to what else I should try? How much does the overlap (crashing) affect the stress solution or the displacement magnitude solution? Thanks for your help, I appreciate it. jhc

I got an error message: no data could be found in your post.
I will try a compressed file. jhc
Okay then, 1x is the test. I had bee looking at a higher magnification. I usually lower the default magnification. I lowered the magnification to 10x and saw a much slighter overlap. I agree, when I look at 1x there is no visible overlap.
Thank for your help. jhc
Thanks again for your help. jhc
Other aspect is the mesh. More gradual transition could lead to a better results
PS Now I have to read again the list of new features because they are many
