Hello everyone,
I have a problem with chtMultiRegionFoam regarding the fvOptions file. I would like to impose a heat volumetric generation in PART of a region. (When I use the cellZone mode in fvOptions selecting one entire region, the code runs well.)
The problem starts when I try to use cellSet mode and select a cellSet that I generate in topoSetDict:
- if I put the topoSet file in "system" folder, it creates a "sets" folder in a "polymesh" folder OUTSIDE the regions folders and not inside a "polymesh" folder of a particular region (where the heat source should be); this causes that openfoam doesn't find the cellSet because the fvOptions file is inside the folder of the region where the Eeqn should take the source from.
- if I put the fvOptions file outside the regions folders in "constant", then openfoam finally finds the cellSet, but the heat source is completely absent in the simulation, as fvOptions is not associated to any Eeqn.


does anybody know a solution?
I also tried setSet but still there's no heat generation.


thanks to anybody who's willing to answer
