I am currently working on natural cooling of Li-Ph cell using chtMultiregionfoam solver , with a const semi implicit heat source. On solving its showing unknown model type ERROR.
When i run chtMultiRegionFoam , it's showing following error

Hey


If you are using a multiregion sovler, the fvOptions file needs to go in system/region1 instead of constant. I guess this could be the reason why OpenFoam could not locate your file. It also means that the fvOptions file applies only to its region, and you should write one fvOptions per region if needed.

Faced the same problem. Did you find the cause of the error?
