Hi, I modelled turbulent flow and heat transfer in a 3D pipe in Ansys-Fluent. During post-processing in CFd-Post, I need to obtain local heat transfer coefficient on inner wall. For that I need to make about 200 cross-sections at different axial locations. Is there any way to make these sections at once rather than doing manually one by one. I have to do same operation on 20 other cases.

I also have to make same number of poly-lines in domain. I guess, method to do that would be same as that for multiple cross-sections. Any suggestion is appreciated.

Regards.

Well, I am not an expert user and I don't have ANSYS by hand. But maybe you can try journals.

how you will compute different parameters on these 200 sections?

why not try UDF?

Journaling and scripting might work, but I have no experience in that. I will try that. Thanks.

I would manually create each of 200 iso-surfaces and corresponding poly-lines and export the excel file containing local heat transfer coefficients at each poly-line.

Can we use UDF to create multiple iso-surfaces for post-processing? Or you mean that create a formula or an expression at required locations to directly obtain these local coefficient in a text file, before initialization of simulation. Thanks.
