Hello,
In the picture below you see a steel sheet exiting a liquid zinc bath with a constant velocity of U.

The initial thickness of zinc on the steel plate is too much, so we use a solid barrier over the bath which controls and reduces the coating thickness.
I want to find the shear stress and pressure gradient distribution over the RED line.
I used the shown boundary conditions for the simulation in COMSOL.
Are the B.C(s) OK?
Thanks.
