Wow - seriously? I must have misread the recent discussion. I knew you were working on that but I didn't think we were there already. Are the elements allowed to share nodes and/or neighbor each other? Could you get a test case into our examples/ before I inadvertently break this? > You can initialize libMesh with different communicators on different > processors.... but you will have a hard time getting those two > "subsections" of processors to talk to each other.... Getting them to talk to each other is easy enough; you can create a new Parallel::Communicator from MPI_COMM_WORLD and then all our friendly helper functions should work with that. Getting the communication efficient will be a bear in any case, though; you'd have to construct your own send_list connecting completely independent partitionings. --- Roy ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
