Hi all,
i have done a cfd simualtion of internal flow with fan modelled usingMRF. Now i have to get some range of velocity angle of vectors wrt to radius of Mrf(Fan). i have use this as an input fro fan in other simulation tool. Thanks in advance regards Far |

Is it possible to define a Custom Field Function? You might use the x-velocity, y-velocity and z-velocity to calculate (a field) of the desired angle.
Good luck! |

choose the MRF zone as reference volume. velocity then can be expressed as axial velocity, tangential velocity and radial velocity. you can define a new user defined function, such as, angle-of-velocity
angle-of-velocity = arctan(radial_v/tangential_v) This may not be the exact thing you want, just a hint. |
