Dynamic Mesh
- Let’s tune the properties of rotating motion.
- Edit constant/dynamicMeshDict and set up the rotatingMotionCoeffs.
- The listing of appropriate dynamicMeshDict follows:

- Apply this rotation properties to the cellZone ‘rotor’, which was created during the mesh generation of the rotating part using topoSet utility – see section
