Hi,
I have convert a fluent mesh to openfoam format (see picture). How I can create a rotor zone in openfoam ? Thanks |

1. by block. U should name the rotational block and stationary block. then openfoam will tell these two different zones. 2. by tet mesh U should draw a interface like a cylinder, then name it as rotational body, the others as stationary body, then compute tet mesh, you will have two zones. Best, |

Hi,
I have done this step under ANSYS MESHING (i have two rotor zone and one stator zone). but when i execute this instruction fluentMeshToFoam stirredtank.msh The boundary (interface) of two rotor zone is merged into one new patch "default_wall" Thanks Code:
