Hi, I'm using ParallelMesh to discretize the Poisson equation. I want to integrate a certain quantity over each element. That quantity is not available for all quadrature points of some elements on one process (such elements are ghosted), so I sum the parts which are available in respective processes for that particular element and MPI reduce the sum to get the complete integral.
Now to be able to do this, I have to identify the elements for which the integral has to be MPI reduced. Can anyone help me with how the element can be identified? I tried using elem->id() but I get an exception in DofObject::id(), since the _id == invalid_id. Thanks, Harshad ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
