While attempting the multiRegionHeater chtMultiRegionFoam tutorial I encountered an error that I cannot resolve.
After running the Allrun file, the log.changeDictionary.bottomAir file displays the following: Quote:

I solved the error by replacing line 18 of the Allrun script:

Now I have a new dilemma. The various volume fields will not show up in ParaView. Suggestions? |

Greetings Matt,
Quick solution: on the first line of the Allrun script, change "/bin/sh" to "/bin/bash". Long explanation - The problem you are facing is quite simple: all of the tutorial scripts use "/bin/sh", but in each Linux distro, sh is linked to bash, dash, ash, ksh or any other shell. But unfortunately, the Linux distro where the tutorials were prepared, sh points to bash, thus the scripts respect mostly the bash syntax, while other systems that use another shell can't handle that same syntax; e.g.: Ubuntu that has dash as default sh. If you want to change all tutorial scripts to use bash instead of sh, you can run this code in a terminal with OpenFOAM environment activated: Quote:

Thank you for your reply, Bruno
I am still having the same problem. The solver - chtMultiRegionHeater - runs, but when I try to view the volume fields in ParaView they disappear after the initial time. |

I have the same problem that m.nichols19. I use OpenFOAM 1.6 and I don't have the foamTovtk application. Is it normal ?

Hi wyldckat, thank you for your answer.
Indeed, I have the foamToVTK application. When I run it, Code:

Hi, everyone!
I don't find the VTK folder in chtMultiRegionSimpleFoam but I do find it in chtMultiRegionFoam. Can I copy this one to the other one? Or is there a huge difference between the two? Regards Marco |

I will need a few more details before I can answer your question, marval. Does running foamToVTK not create the VTK directory in your chtMultiRegionSimpleFoam case directory? Did you run the same case using both chtMultiRegionFoam and chtMultiRegionSimpleFoam?

Hmmm, I really don't know how this works but when I use the Allrun script the VTK folder appears.
It doesn't look that I need to use foamToVTK to view my results, do the Allrun script do it? Because I don't see anything in the script though. I hope I'm not too confusing. Regards Marco |

The VTK directory created by the Allrun script is irrelevant. You will need to run
Code:
foamToVTK -region |
