Hi,
I have found this document on Code_Saturne website Mesh_Generation and as it is not dated and referenced on Code_Saturne website, I have not found any information in the actual v7 guides, so are the information related on the mesh generation still valid ?
More precisely, is it better to use quad based/hexa meshes or triangle based/tetra meshes with Code_Saturne ? I thought that hexa were better but in the document, it is stated that :

For RANS computations, at least, a good mesh consisting of tetrahedra (a fine mesh of equilateral tetrahedra) is a better choice than a mesh of hexahedra containing non-orthogonal cells.

Is this document up to date ? I get poor performances with tetrahedra whereas hexa meshes work nice
