No, currently the BDF exporter always re-indexes the nodes. Changing this behavior would entail replacing * _index by _num in MVertex::writeBDF() * getVertexBDF(i)->getIndex() by getVertexBDF(i)->getNum() in MElement::writeBDF() Now that the default Gmsh mesh format (MSH 4.1) does not use such a re-indexing scheme anymore, so it could make sense to change all the other formats to follow suit. You could maybe open an issue in our Gitlab tracker to request this, so that we keep track of the issue? > I tried the Mesh.Renumber option but it didn't work, This option governs the renumbering of nodes/elements when Gmsh generates meshes, not when saving them.
