Oh. I think the dimension flag should be -2 rather than -3 for plane problems, although if there aren't any volumes in your geometry that shouldn't matter. Anyway, try the following example; FreeFem++ seems happy enough with it. Besides the three input files (oblong.geo for Gmsh, 3to2.awk for Gawk, and oblong.edp for FreeFem++), I also attach a picture of the mesh as plotted by FreeFem++. gmsh -2 -format mesh -string 'Mesh.SaveElementTagType=2;' -o oblong.3.mesh oblong.geo gawk -f 3to2.awk oblong.3.mesh > oblong.mesh FreeFem++-nw oblong.edp
