I'm working in a 2D model where a circle is compressed inside a groove that is pushed (see picture below). There needs to be 2 contacts declared: one between the groove and the circle; and the other one between the circle and the rectangle that is the one compressing it.
I have tried declaring a General Contact as the rectangle and the groove are the same material, but I get the following two warnings in the .msg file:
***WARNING: THERE ARE 2 UNCONNECTED REGIONS IN THE MODEL.
***WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE C4.348 D.O.F. 2 RATIO = 250.029E+12 .
If I declare 2 surface-to-surface contacts for each one I get the same two warnings. The thing is, I don't know which contact is not detecting. Can someone help me?
Thanks :)
Hi Julia,
