How to compare temperature difference at same position between two cases?
 

Hi,

I have used ke-RNG model and low-Re model to simulate a case using same mesh and same boundary conditions, and I want to compare temperature difference at wall surface, and I want draw a contour of delta-T.

I have tried to use TECPLOT 360, but it can only load one case so I cannot use date>>alter to calculate delta-T.
Then I tried to use CFD-POST, it is easy to compare difference between two cases, but I have done many post processing before, so I'd like to use tecplot to plot the delta-T contour.


How can I do this use?

Thank you in advance for any information!:):)

Hi,
Can you explain how you manage to do it in CFD post? I am trying to calculate delta T for the same case but different bc's. Thanks in advance.

If you do not need a visual confirmation of your DT you should be able to get the data directly form each data file in Fluent.

In any case, open one of the cases on the CFD-Post. The click Load results again, before loading the new file you must select the option "keep current cases loaded".

Thanks for quick reply,
I did it by using, simply, temperature@case:case1_Tadiabatic -temperature@case:case1_Twall
It generates a warning but works fine.
