chtMultiRegionFoam example
 

Hello everybody,

I would like to test the chtMultiRegionFoam example written by Bernhard Linseisen. I simplified the example to chtMiltiRegionalSimpleFoam with just one solid and one liquid region.

I successfuly did:

splitMeshRegions -cellZones -overwrite

Then (the tutorial says) i should remove the solid fields from the fluid regions and the fluid fields from the solid regions - I dont understand this, where are those field and regions? I did read the Allrun script ( rm -f 0*/$i/{mut,alphat,epsilon,k,p,U,p_rgh} ) but there are no "mut,alphat,epsilon,k,p,U,p_rgh" files in solid region and no "Ychar,Ypmma" files in liquid region of 0 folder.

Then i successfuly run the chtMultireginSimpleFoam solver. I got the results, but when i try to view them using paraView, I get an error:

---- paraView error messages -----------------

Any idea what is wrong? Any help will be appreciatid,

This was tested on bluCFD (openFoam for windows). There was no such error in linux installaion.

Hi,

all parameters you mentioned are in o directory of your case, then they copied and modified for every region, so you must exclude parameters don't belong to region.

when viewing your case in paraView you must load every region.openfoam file created in the end of running by command paraFoam -touch $region
you can load them by clicking on open in tool bar.

good luck;
