Hello everyone.I have performed a set of validation simulations using Fluent to compare the numerical results with the experimental results.The steady simulations have been performed on a periodic geometry using translational periodic boundary conditions in Fluent. So far it’s going all right. My main intention is to perform simulations for parametrized geometries using the Design of Experiments methodology in ANSYS. I am able to parametrize the mesh and geometry, but I am not able to parametrize the mass flow rates in the periodic simulations input conditions. For velocity-inlet or pressure-outlet BCs, there seems to be the “P” logo which means that I can parametrize that particular quantity, but in the periodic flow BC tab, there seems to be no “P” symbol in front of “Specify Mass Flow rate” input box.Is there an way I can parametrize this mass flow rate?
UPDATE-I went through the the use of "custom-input-parameters" using beta features in Fluent. I played around a bit with the Scheme programming(because that's what an ANSYS presentation showed) and it didn't work out sucessfully. I also realized that since I want the pressure gradient as an output parameter, I will have to again play around with the Scheme programming, of which I don't know anything.
UPDATE-I got it working after playing around a bit with Scheme programming and looking deep in the manual. This is the link I referred to.

Hi, I also met this problem. I think my input parameter for mass flow rate is working, but I have no idea how to set the pressure gradient as output parameter. Could you share with me your solution for this problem?
Thanks a lot!
I got it working with setting mass flow rate as an input parameter. However, still no clue about setting pressure gradient as output parameter. Looks like I cannot use scheme procedure to set output parameter. Shall I use udf to do this?
Thanks!
You should use the same approach by modifying the code to output the pressure gradient.
