CEL - Compare Cases

D2Net15 · October 15, 2014, 08:45

Hello everyone,
I´m using ANSYS 15 and i want to compare two cases with identical geometry and mesh. Therefore i want to make a CEL Expression which makes a difference of the Wall Heat Flux. I thought about something like this:

Test = Wall Heat Flux@Side1Case1 - Wall Heat Flux@Side1Case2

I know it´s not working like this, but i can´t imagine, that it is impossible.
By the way, to make an averaged solution is not appropriate, because i want a difference for each node.

Don´t hesitate to ask, if you have problems in understanding my problem.

Thank you in advance.

If you have already loaded both cases, active the "Case Comparison" mode. This mode automatically creates a variable named "Wall Heat Flux.Difference" between the two cases being compared.

Then, you can plot Wall Heat Flux.Difference at any boundary locator.

Is this what you intended? correct ?

Hope the above helps,

Thank you, for your fast answer.
I´ve already tried that, but there is no Wall Heat Flux.Difference. Can i specify the affected variables?
