[Nek5000-users] Stream function

[nek5000-users at lists.mcs.anl.gov]

Hi All,

I am reading in a Nek output file to postx, and would like to compute a streamfunction in postx and save that to a file format I can view in Visit.

After I select “DUMP vtk ALL”,  the resulting VTK file only contains a “VORTEX” and a “PRESSURE” variable when I plot it in VisIt.

I think I might be doing something wrong. Is there some other way this could be done in either Visit or ParaView?

Thanks,

Hannah
