HI Zhang, That has been done with PyFR with Catalyst doing everything on the GPU. I see some stuff at https://github.com/vincentlab/PyFR-Catalyst that may be a good starting point for you.
I don't quite know if Catalyst is ready for general use at this point on GPUs (it may be but I haven't done it so I can't be sure). As Catalyst development continues though it will be made much easier to effectively use the GPU in situ. We will probably be using VTK-m for that. If you want to go ahead with this effort, the ParaView mailing list can probably be quite helpful.
