LibMesh uses the vtkXMLPUnstructuredGridWriter, so it requires a VTK that is built with MPI enabled, using the Cmake flag shown above. However, that's not the only reason that linking can fail. To check the exact reason, you'll need to look at the config.log or post a link to it so I can take a look (unfortunately, no attachments are allowed on this mailing list). > > <<< Configuring library without VTK support >>> > > Second, if I save a mesh and a solution as "output.e" for exodusII format, > parview reads only the portion that belongs to processor #0.

The Exodus writer serializes DistributedMeshes when writing, so you should get one mesh file with the entire contents of the Mesh in the case you are describing. -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
