Hi Foamers

Dear Ata,
I am not a coder, but do know of a boundary condition in src/finiteVolume/fields/fvPatchFields/derived/... known as "movingRotatingWallVelocity" which exists. I am not able to locate in my 1.5 version, but others are getting it to work. Best, Lori |

Hello lth
Thank you very much. That's true. I see. It is in OpenFoam-dev not in OpenFoam standard. Best regards Ata |

There is a rotatingWallVelocity boundary condition for in the standard OpenFOAM 1.6 and 1.6.x releases. Apply it like so:
wall { type rotatingWallVelocity; origin (0 0 0); // origin of axis and the axis axis (0 1 0); // about which the wall will rotate omega 25; // m/s } For moving walls: wall { type movingWall; value uniform (1 0 0); // wall moving at 1m/s in x direction } Hope that helps. |

Hi Ata,
Ignore the boundary condition for movingWall as it doesn't work. Instead, just set it to fixedValue and provide the correct velocity vector. Good luck! Cheers, adriano |
