Hi Bruno, I avoid this iso.msh file but it still not work. Maybe I should mention the whole way how this isosurface is constructed.
1. Grid is constructed by dealii -> saved as grid.vtk 2. grid.vtk is read by vtkUnstructuredGridReader -> construct isosurface with the vtk class vtkContourGrid (3. saved isosurface as iso.msh) 4. convert it by tethex and save it as "iso_quad.msh" 5. read it in dealii For a refinement ref = 1 of the dealii grid (see 1.) it worked. But for ref > 1 the above mentioned error happens. I do not really understand how this not correctly cells are created since I thought that tethex takes care of that. Do you have any further ideas?
