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?

Opaque will become famous soon enough
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.
