Heat Flux as a Profile Boundary Condition
 
Hi Everyone!

Does someone know how to set a heat flux as a profile boundary condition?
I have a heat flux profile in the correct csv format (x[m], y[m], z[m], Heat Flux [W m^-2]) and I want to use this profile as a boundary condition at a wall. I've initialized the data under Tools -> Initialise Profile Data, that worked out well. CFX has now the cordinates (x,y,z) and the Heat Flux. In the next step I want to use the profile data to specify the boundary condition at a certain wall. In Basic Settings I select "Use Profile Data" and the initialized file appears. But then nothing happens.... Does someone know how to proceed??? That would help me alot!

My guess (and it is only a guess) is that the profile data only supports velocity. Have you tried a 3D CEL interpolation cloud function? I think that should work in this case.

Thank you very much for your answer, I found out how it works. You have to specify the variable under user defined functions, and then it works.
