viewfactors in parallel?
 
First: Sorry for duplicate posting - I just accidentally posted the same as a reply to an older existing question - but in the OpenFoam Forum, instead of Running, Solving, CFD...

My question is, has anybody successfully run S2S radiation problems using the viewfactor method in parallel?

I am failing with the file "FinalAgglom" missing in the processor subdirectories, and have no idea how to decompose or distribute that.

Thanks a lot for any hint!

Found out myself - but as I have seen others asking the same: The trick is to run faceAgglomerate and viewFactorsGen also in parallel, after decomposing the case,
and with the same number of processes ...

I've moved your latest post to this thread and deleted the other post, as it was more incomplete and as you've indicated, was an accidental post.

Thanks for sharing the solution you've found!

Best regards,
