Hello all,

I have to solve some heat transfer cases that are softly coupled, e.g. there is a more or less steady flow field and a transient temperature distribution. I tend to run this with the frozenFlow flag turned on in chtMultRegionFoam and using a fixed/fozen flow field. This turns calculation time from months into hours for my problems.
However, as there is some effect in flow field by thermal distribution (e.g. density changes) I am looking for a way to solve the fluid flow from time to time (every 2,5,10,20,...time step for example). Is there any straingthforward way to do this out of the box or does it require me to modify chtMultiRegionFoam? Thanks.

Best regards
