Hello,

I am trying to use Karamba3D for my research, but I want to validate the results, so I constructed a simply supported beam (analyzed as shell for now) and got its deflection.

The theoretical solution is 170.97593 mm (using beam theory), and the following are the results from Karamba3D:

- x axis: mesh size in m
- y axis: deflection

Why am I obtaining weird wiggly shape in the convergence study and how can I solve that?
