Hello. I found this ASCII diagram in a C comment on lines 317--332 of Geo/MQuadrangle.h. /* * MQuadrangle * * 3--3+3E-...--4+2E--2 * | | E = order - 1; * | | N = total number of vertices * 4+3E 3+2E * | | Interior vertex numbers * ... 4+4e to N-1 ... for edge 0 <= i <= 3: 4+i*E to 3+(i+1)*E * | | in volume : 4+4*E to N-1 * 3+4E 4+E * | | * | | * 0---4--...---3+E---1 * */ I think it should specialize to the case you want for E=2, so that, for example, along the bottom we'd have 0, 4, 5, 1. _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
