Hi foamers,
As we know, if we want to simulate MRF situation in fluent of CFX, we could launch two mesh project seperately, and one of the mesh is named rotating zone mesh and the other is stationary zone mesh, and assemble it in pre-process. you dont need to merge nodes. But afaik,that does not be suitable for OpenFOAM, so you have to generate one mesh which is divided into rotating zone and stationary zone in ICEM.then merge nodes. after that process, the quality becomes very bad. then you have to smooth it.... So the problem is : Does OpenFOAM can handle that interface problems like in FLUENT or CFX, I dont want to merge nodes. |

hi
You mean interface sliding mesh between two mesh parts?i had same problem but i assumed rotor fixed and i gave the motion to boundary means stator. |

No, I just want to use MRF to simulate.dynamic mesh is a little complex. but if there is a tutorial I would try. thank you anyway.

I think may be GGI is what you want? You can search GGI in the forum
