Moving Heat Source on CFX

Hello!
I am trying to simulate friction stir welding on CFX and I wish to create a moving heat source. On COMSOL Multiphysics that was achieved by applying a translational motion with steady velocity (along x-axis) to the heat transfer. Is there a similar way to do so? I have also thought that instead of applying velocity u on the heat source, to apply velocity -u on the coordinate system. Is it possible to create a moving coordinate system on ANSYS CFX? Or in general, how can one create a moving heat source on ANSYS CFX, in terms of a heat flux having a translational motion? Last edited by nagas; May 3, 2018 at 10:50. Reason: add tags |

You can model it as a heat source moving, or a transient fixed (space) heat source
Write a CEL expression for heat source as a function of time along the boundary. Such expression should include the speed of the moving source and time to determine the location, as well as the strength of the source. |
