"WebThe slip boundary condition erases the normal component of the variable at the patch and keeps the tangential components untouched. It is very similar to the symmetry. Keep in mind that the symmetry is a boundary type, whereas the slip is a boundary condition which can be applied on boundary patches of type wall and patch respectively. " - Openfoam slip wall
