hi, Im modelling fluid pressure on membrane using ABAQUS. When I go to Load module / Type: Pressure / Distribution: Hydrostatic, it asks for Magnitude, Zero pressure height and Reference pressure height.

What does each of these represent exactly?

Is it true that in the case of water pressure, P = pgh where p = 1000kg/m^3 (density water), g= 9.81m/s^2, h = 1m (does h vary??), So P = 9810 Pa, but since im using [mm] i should use P in [MPa] so I should write 0.0098 in Magnitude?

What does zero and reference pressure height mean exactly??
