Hi
I want to compute the turbulent around a cylinder array inside a channel. I've a fine structured grid but I'm not able to find the proper combination of inlet/outlet to solve this : I always end up with diverging time step continuity errors. I tried many combination : - fixed inlet and Neumann outlet for U, Neumann Inlet and fixed outlet for P - massflow inlet and Neumann outlet for U, Neumann Inlet and fixed outlet for P - fixed inlet and Neumann outlet for U, Neumann Inlet and outlet for P - fixed inlet and massflow outlet for U, Neumann Inlet and fixed outlet for P Nothing is working. If anyone has an idea, I take it. Many thanks Yannick |
