How to put pressure when using cyclic boundary condition
I am using interFoam solver with cyclic BC in streamwise direction. While using cyclic BC I want to impose pressure gradient in streamwise direction . Is there any method to do so ? kinldy help .
I think you can give mean velocity. Check pimpleFoam/LES/channel395 tutorial case for reference.
In order to avoid very long pipe(domain) I want to use cyclic BC . Apart from that I am also interested in instability study which require cyclic BC to be implemented in streamwise direction . regards, Irwin
