• Rotation properties are set in file system/fvOptions

   

• MRF method is always applied on certain cellZone which is called e.g.: rotor_mrf_zone

   

• nonRotatingPatches list defines those patches from the selected cellZone, which are not rotating

   

• Parameter origin is a point defining position of axis of rotation

   

• Parameter axis is directional vector of axis of rotation

   

• Parameter omega is angle velocity in radians per second

   

File system/rotor/fvOptions for turbine rotor may be following:

    active          true;
