Wall Calculator Film Coefficient Greyed out

Anonymous — Fri, 10 Apr 2015 18:46:29 GMT

Hi,

Anyone know why the wall calculator film coefficient box is greyed out. It will not let me calculate a film coefficent for this design scenario. In my other design scenario, (The exact same setup except the heat generation boundry condition is higher), it works just fine. I am not sure what I have done to prevent me from seeing this information. The solutions are both Steady state flow and thermal analysis.

Thanks,

Grant Chapman

Hi:

If the scenario is stopped, can you try closing the UI and then reopening the study to see if that resolves the issue?

I saved, exited CFD, and reloaded the model. I am getting the same issue as before. With the exception that the check box is no longed checked under the grey.

Can you repeat the issue you are facing with a simple model and let us know the steps involved? If not, try cloning the scenario and see if the issue persists.

Hope this helps a bit.

Hi,

This was escalated to a case and I will email Grant directly to help.

We will post back here once we know the solution.

Update: This appeared to be a one off problem and has not reared it's head again 🙂
