Splitting interface patch to enable option for mixingPlane BC - Rotor Region

There are two approaches to stator-rotor interface:

  • Frozen Rotor – direct mapping between stator and rotor
  • Mixing Plane – special averaging and then mapping between stator and rotor

To enable Mixing Plane option the interface patch is split into certain number of other patches – rings. Frozen Rotor option can be applied anyway (whether the interface is split or not).

When the data are prepared using topoSet utility, the patch is split using utility createPatch. First create configuration file topoSetDict, then run topoSet utility:

1 3 sh genTopoSetDict.rotor.sh > system/topoSetDict
1 3 topoSet

Create configuration file createPatchDict, then run createPatch utility:

1 3 sh genCreatePatchDict.rotor.sh > system/createPatchDict
1 3 createPatch

New mesh is located in directory 1, copy it to constant/polyMesh:

1 3 cp -rf 1/polyMesh/* constant/polyMesh/
1 3 rm -rf 1
