when i use the tui command

mesh/modify-zones/make-periodic

wall1

wall2

how would I know if it created a conformal periodic or not? is there any way to cross-check?

You should create periodic zones before bringing your mesh into Fluent Solution mode to ensure it is conformal.

For example, if you use the Watertight Geometry workflow in Fluent Meshing: 3.6. Setting Up Periodic Boundaries (ansys.com)

I see..but I have already created the models and i am doing this

I have many models for which i have to create periodic boundaries so i can't go ahead and change all the mesh now. is it possible to do this with TUI?

when i use this command 

mesh/modify-zones/make-periodic

i get an option to pick translation or rotation and give distance vector but i did not see the option of conformal or nonconformal coming up on the console when I used the TUI command.

I just ran a test on my end and I am unable to make periodic zones using the TUI command if the number of elements do not match between the 2 zones. Additionally, creating a non-conformal periodic zone will create a Mesh interface. So perhaps there lies your cross-checking.

I invite you to try this, if you do not have a Mesh interface after creation of the periodic zone, it would suggest that the 2 boundaries are conformal.

Actually, you can use this command instead 

/mesh/modify-zones/create-periodic-interface

This command gives you the option for Conformal/Non-Conformal

/mesh/modify-zones/create-periodic-interface command worked.

Thank you so much for suggesting this.

Happy to help! :)
