I have posts and answers on this topic, but not sure if my situation has been covered and explained. The help only has one example for a liquid in a tank, which does not apply here. I am applying hydrostatic pressure on an acrylic panel that will be set in the wall of a swimming pool, in order to determine the thickness of the concrete and required rebar...SO, I define the hydrostatic pressure on the concrete wall & acrylic panel, the point on the surface, direction where the depth varies, and I add 14.7 psi for atmospheric pressure and get results.
The problem is that I am an order of magnitude greater deflection than the acrylic panel manufacturer. The question is, should the surface pressure be 14.7 psi or 0 psi?
Thank you anyone who can help me understand how the surface pressure is implemented in Nastran.
