Dear all,
i have a problem. I try to simulate a fluid flow effected by a boundary stress on a key hole. See attached mph-file.
With a very big mesh, comsol solve the problem. But with a smaller mesh, comsol does not solve the problem any more.
Have someone an idea why? Or what i can change to get a better convergence with this problem?
Thanks to all.
Best regards
Johannes
