Thank you very much. I know for the hydrostatic pressure, but I want to do dynamics after static so I keep the body and wanted to know if with the body there is hydrostatic?
I have an other point on the design. I want to add beams for the roof of the structure. When I do modal I observe that the beams are not connected to the walls. I share the topology and it's marked but in static and modal analysis it's not connected...
Here my model.
