Hello!

I am currently using mmg2d to generate anisotropic meshes based on a Gmsh file only, with the metrics given as NodeData, the final goal being to then generate P2 (curved) triangle meshes. I’d like to work with a straight P2 mesh from the start (6-node straight triangles), but I understand MMG only deals with Gmsh elements with type 2, 4 or 15 (tri, tet, node). Is there a way to launch mmg2d with a Gmsh .msh file made of type 8 and 9 (2nd order lines and tri)? I would provide metrics at high-order vertices, even though I expect only metrics at P1 vertices to be considered for adaptation.

Thank you for your time!
