[Paraview] OpenFOAM and ParaView

[Berk Geveci]

Hi Greg,

There seems to be some remnants of the other OpenFOAM reader
somewhere. I tested to make sure and I can open the only .foam file I
have without problem (I would be happy to try yours). At first glance,
I can see that the .pvs script you are using has a problem. The reader
module in paraview is called OpenFOAMReader and the one in the script
is FoamReader. Replacing that should fix the script. I cannot tell why
you are getting this error when you do File->Open. Maybe the ParaView
you are using was modified? I would recommend downloading it from
paraview.org and trying it out.
