Therefore I made a simple Cylinder mesh and used the StressSolver and the MeshSolver. The StressSolver works well but the MeshSolver does not seem to change the Mesh at all.

Here I will post a part of my Sif file:

Solver 1 is the StresSolver which does not do anything at the moment, because I want to resolve the Issue with the MeshSolver first.

Solver 3 is the ResultOutputSolver so i can see the result in paraview.

I have therefore not inculded them.

Code: Select all

```

I would really appreciate some help. I Do not know what i am doing wrong.
