Andy, I wasn't setting up the server or anything. I have just been connecting to one of my preset configurations. The velocity data shows up fine but for some reason when there is more than one processor working on the visualization Paraview can't read it.
Here is the error: ERROR: In /p/home/angel/PV/4.3.1/Build_4.3.1_osmesa/paraview/src/paraview/VTK/IO/Xdmf2/vtkXdmfHeavyData.cxx, line 1128 vtkXdmfReader (0x104ae20): Failed to read attribute data The setup has just been clicking the connect icon, the system, and choosing the number of nodes and processors per node. If it helps I'm on Paraview 4.3.1 64-bit. Sorry I am pretty new to all of this stuff. Slowly getting the hang of things.
