Translation the domain by CFX
I am looking for the answer about the translation by CFX-pre. My geometry is quarter pipe (inlet-velocity is boundary condition for axial inlet) with perforation at upper surface (mass flow rate for radial boundary conditions) and outlet-pressure for outlet pipe at 120" long. Please I want to extent this pipe to 2 copies i.e. to be 3 domains (one total domain) the total long is 360".
Now for the new domain one axial inlet (inlet-velocity at the beginning of the pipe) and at the end of the total domain is (outlet-pressure). My question what I will put the boundary conditions for the interfaces between 1 and 2, 2 and 3?
