Hi foamers,

I am having difficulties in using paraview/parafoam in OpenFoam 1.5 - dev in Ubuntu 8.1. Until now, I tried to recompile paraview and the PV3FoamReader utility following the instructions available in the OpenFoam main site and other information available at the forum

However, I was unable of installing paraview, and consequently parafoam. What should I do? I am planing to download paraview, install it, and then change the configuration files of PV3FoamReader to be able to use paraFoam.
Can I do this? Is there a better option?

Regards,

António Martins

Hey Antonio, did you end up getting paraFoam to work? I'm interested in the solution too...the buildParaView3.3-svc doesn't work in OF-1.5-dev which is very annoying.

Hi James,

I got it to work too with OpenFoam-1.5-dev (Ubuntu 9.10 x86_64). It turned out, at least in my case, that buildParaViewFunctions in $HOME/OpenFOAM/OpenFOAM-1.5-dev/bin/tools/ contained some error(s). I replaced it with buildParaViewFunctions from OpenFOAM-1.5 and it worked . The working buildParaViewFunctions looks like:
