My first question is about the mesh quality in the context of SEM. Should I have a mesh with the same quality as in FVM? Is there any specific index to consider when dealing with tet and hex meshes in Nektar++? I have seen a very skewed tri mesh in one of the tutorials. Could you kindly provide some insight on this? My second question is specifically about NekMesh. Is it possible to smooth the mesh of a wall-mounted cylinder using high-order cylinder module? Or would you suggest to use spherigon module for that purpose? Kind regards syavash
