Symmetry in flow simulation

Hi, Everybody

In the stress simulation, such as static, we always use symmetry to simplify the simulation, when the part is symmetrical and the condition is symmetrical too. However, I always doubt whether the symmetry also works in flow simulation.


For example, there is a high-speed flow in a pipe. The turbulence always make it complicated, and not symmetrical in the real test. Should we use symmetry only in low-speed and laminar flow?
