snappyHexMesh on a multiple region blockMesh

Hello everyone.
To quickly mesh an impeller rotating in a stirred tank, I would like to use snappyHexMesh on top of a structure blockMesh which encompasses the AMI interface. I Have already made the structured blockMesh that has the AMI patches and a rotating cylinder of fluid in the middle. Everything is fine. However, when comes to time to use snappyHexMesh, if the point "inside" that I specify is within the rotor region, the entire stator region. It seems that snappyHexMesh only detects the region in which the locationInMesh point is in. Do any of you know a work around to this issue? (namely keeping the two regions...) Cheers, Bruno |

I think your problem is quite similar to mine in some points. Now I am dealing with rotorDiskSource but I have obtained a valid wind turbine mesh with the blades meshed and so. You will need a cylinder STL geometry to define that all the cells inside that cylinder will be a new cellZone. Inside surfaceRefinement: rotating { level (1 2); cellZone rotating; faceZone rotating; cellZoneInside insidePoint; insidePoint (0 0.1 0.5); |
