Visualization issue on intersection of slip (Euler) and no-slip walls

Describe the bug
We noticed that the symmetry boundary condition is showing a different behavior between sequential and parallel run. With the parallel run, the skin friction lines become parallel to the symmetry wall. We reproduced the issue on a naca0012 profile extruded between two slip walls.

cfx_comp1
cfx_comp2
cfx_comp3

The convergence of the residuals is not good and is similar between sequential and parallel run. The drag coefficient is also taking a long time to stabilize. During convergence, the skin friction lines are much more deviated at the cell touching the slip wall but it improves with iterations (for both sequential and parallel runs).
