post processing heatExchanger from chtMultiRegionSimpleFoam

I have successfully ran the simulation of heatExchanger on OpenFOAM 2.2.x using Allrun-parallel script. Now when I type paraFoam in terminal I get the following error:

p, li { white-space: pre-wrap; }

Code:

ERROR: In /opt/OpenFOAM/OpenFOAM-2.2.x/applications/utilities/postProcessing/graphics/PV3Readers/PV3FoamReader/PV3FoamReader/vtkPV3FoamReader.cxx, line 216

I have two compiled Paraview (both are 3.12 version)
- one compiled with OpenFOAM 2.2.x with system QT
- second one compiled with OpenFOAM-1.6-ext with ThirdParty QT

when I use the version compiled with 1.6, I have no problem. the problem occurs with 2.2.x version. Could system QT be the reason behind this?

Greetings Daniel,

It depends on the Qt version you have on your system.
But from the error message, my guess is that either the mesh is not existent or that it was generated in a format incompatible with 2.2.x.

Nonetheless, since you're talking about a multi-region case, it's possible that you are not opening the correct files. If you:

Run:

Code:

paraFoam -touchAll
Then:

Code:

paraview
Once in ParaView, open the files that have brackets in their names and you should now be able to see each mesh region.

Best regards,
Bruno
