Do you have an if-statement in your assembly function that assembles different PDE terms depending on what subdomain you are currently on? How is your boundary subdomain actually coupled to the volume? -- John ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
