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?
