How to activate the viscous heating effect in a simulation using Hyperworks CFD.

I have seen in a tutorial that it was possible to take into account the viscous heating effect created by the flow of a viscous fluid. I don't know how to activate that function inside Hyperworks CFD. Is it even possible ? 

While checking into the INP document generated by the software, I can see indicated "viscous heating : off". Can I change that?

Thanks for helping.

    The options to activate viscous heating (and/or compression heating) are not yet available in the HyperWorks CFD GUI.  That is on the development list.

    In the meantime, you can edit the input file itself in the ELMENT_SET command and set

    viscous_heating = on

    Then you'll need to start the solver from the AcuSolve Cmd Prompt (using the acuRun commands) or possibly simpler from Compute Console.
