It is not supposed to move boundary nodes. I just looked at the source code of MeshTools::Modification::smooth(), which I originally had just assumed was calling the LaplaceMeshSmoother, but it seems to be doing something else, and explicitly takes into account refinement but seems to ignore boundary nodes. -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
