MRF in latest 1.5.x
 
Dear all,

there have been some changes regarding MRF in 1.5.x. I am not really sure aht the latest benefits are. As far as I understand there is no need to have a seperate facezone and cellzone for the MRF anymore? And patchs within the rotating zone are now rotating as far as the are not explicitely set to non-rotating? Maybe Matthis can comment on this?

Thanks?

Yes, boundary faces inside MRFzones are automatically rotating.

Benefits:
- less set-up. Only cellZone needed.
- harder to make mistakes in having non-rotating patches inside mrf zones (main reason why it changed)
- can have patches with part inside, part outside.

Sounds great. To if I give a rotating cell zone OF will do everything right even if the faces belonging to this cell zone are in different faceZones? That is what I am intending to do and it seems to work.
