OF11 convergence issues for MRF zone

ufocfd · January 28, 2024, 04:50

Anyone else encountered solution/convergence problems with MRF zones in OF11 simpleFoam?

There is something wrong since you don't see any rotating surfaces inside the MRF zone.

I have been running a case which has been very problematic, but then I reverted to OF10 and it runs fine.

I'm wondering if anyone else had similar experience. There is definitely some problem with OF11 MRF.

you need to have MRFnoSlip in the U file (in OF11), instead of fixedValue (in OF10), otherwise it wont work.
