Dear developers, Are there any plans to incorporate RCM algorithm in Gmsh some time later, that is a pity that such a perfect tool does not have this capability yet. The sparsity pattern of the FE matrices(especially 3D) generated by Gmsh are pretty bad and this makes life harder for the direct solvers due to fill-ins. Best regards, Umut P.S. I lack enough graph-theory knowledge to implement them myself.
