Hello All!
I'am dealing with turbo-machinery simulations. Reading aroud I've found that mixing-plane model is available in foam-extent long time already. As far as I understand this the so called RC2 model (see"Evaluation of an improved mixing plane interface for OpenFOAM" M Beaudoin, H Nilsson, M Page, R Magnan, H Jasak).
So I have downloaded fe40 and I have tried this model on francis-99 turbine. What I get is some weird results at the mixing-plane interface. This behaviour is described in the paper I cited above, so I'am not surprising.

My question is if there are any news about the development of the RC3 version of the mixing plane model? is it really necessary the RC3 version or the present model works fine and I'am just doing some mistake around?



Did someone else experienced the same or similar as I do?


What about the creation of hill-diagrams using OF with mixing-plane? Looking at these first simulations I'd say it is not enough accurate though I might be wrong as I don't have lot of experience.



Thank you !
