This should bring up a list of sideset/nodeset ids that you can then turn on/off to view the different ones which are available. If you have an Exodus file, you can dump it to ASCII by running the $LIBMESH_DIR/bin/ncdump utility that gets installed by libMesh. In the ASCII output, you will see entries like the following: elem_ss1 = 1, 3 ; side_ss1 = 3, 3 ; which tells you that Elems 1 and 3 both have side 3 in sideset 1. This might also be helpful if you are just trying to figure out which sideset ids are available. -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
