Hi everybody,

Is there any way to do visualization without reconstructing a parallel case?
After all, I understand that paraview can be launched as a parallel job, do the visualization in parallel and send somehow the result to a workstation.
Maybe converting to vtk format first?

Thx for any hint!

Hi Thomas,
A (too?) simple way is to run foamToVTK in the processor-directory you are interested in and view just that part in Paraview. I too would be interested to know if anyone is using the full parallel capabilities of Paraview for multi part viewing.

Actually, the workarounds are only a temporary solution, which in long run for some cases does not work well. If somebody could provide nice explanation how to use paraview in parallel that would be great. Somehow in cases which I was testing, single processor was not enough, therefore I had to switch to Tecplot.

Ah, just realized watching simulation results of parallel simulation without reconstruction was easier than I thought. No need for foamToVTK, just do a soft link to system in each processor-directory and open in ParaView. (I am using the excellent reader Takuya Oshima realeased about a month ago).

(Still nothing parallel about the viewing though!).

Has anyone experience with using ParaView3 in real parallel. So running ParaView3 on a cluster using mpi ???

If so, is it easy to setup?
