Dear All,
After spending a lot of time with modelling of the ercoftac test case 79 by using openfoam7 buoyantCavity tutorial I have found wrong definition of frontAndBack and topAndBottom patches in the blockMeshDict file. May be because of this mistake we have non converging iterations – residuals remaining almost constant during 1000 iterations.
Why kepsilonSST model of turbulence was used in this tutorial? It seems to me that for modelling of buoyant induced flows it is necessary to use buoyantKEpsilon model of turbulence.
Please correct me if I am wrong.


Kerim
