* Solver divergence * Solver divergence
In cases where the Mach number and the lift coefficient is high, a strong vortex flow is generated at the trailing edge of the wingtip. This can lead to local unphysical shocks occurring on one or two cells. Coarsening (locally) the mesh usually works.

This can lead to local unphysical shocks occurring on one or two cells. Coarsening (locally) the mesh usually works. See (Good practise)[tips] to try and deal with theses cases.

Since the meshes are unstructured, they can be slightly different each time gmsh is run. This can slightly affects the results. Particularly, the grid from the test "tbox/meshDeformation3.py" can even contain elements with negative jacobian.
