Fix nitsche restart #1106

Closed blaisb closed 3 months ago

blaisb commented 3 months ago

Description of the problem

Nitsche does not restart when the mesh was generated with simplices. See #275

Description of the solution

Fixes the issue by restarting the fully distributed triangulation for the solid correctly.

How Has This Been Tested?

Still pending a unit test, WIP

Comments

While running this test case I managed to find another bug, which is that the Nitsche model is unable of mesh adaptation once it has been restarted. This bug was there all the time. I will try to figure out something, in the meantime I will try to m erge this PR anyway.

So the mixer example that we are testing is still not working, am I correct? Even with mesh adaptation set to none? With the new deal.II version coming up it will work without restart With restart it will take more work, but this will be a follow up PR
