Hello, I would like to transform symmetric boundary conditions in periodic boundary conditions in fluent. I know that I can not set up the periodic boundary conditions in ansys because when I transfer my ansys file to fluent with periodic boundary conditions, it doesn't work. Thanks

in my understanding the periodic boudary is set at gambit before inputting to fluent;

I did my mesh on ansys. And i can not set the periodic BC in ansys because after i have problems to transfer my mesh from ansys to fluent. Apparently, we can set up periodic BC in fluent, but i don't know how to do
