symmetry and wall (free slip) BC
 
Hi,
What is the difference between symmetry and free slip wall boundary conditions in ANSYS CFX.

This is described in the documentation.

Symmetry enforces zero normal gradient to all parameters, and a slip wall does not necessarily do this. But for most normal simulations they are equivalent.

And a symmetry plane is required to be planar, but a slip wall can be any shape.
