PINSFVSymmetryVelocityBC
Overview
This object implements a symmetry boundary condition for the superficial velocity. It applies boundary forces such that the gradient of the velocity parallel to the boundary is zero in the boundary normal direction. A PINSFVSymmetryVelocityBC should be applied for every superficial velocity component on a symmetry boundary. Similarly an INSFVSymmetryPressureBC should be applied for the pressure on the symmetry boundary.
Implements a symmetry boundary condition for the velocity.
