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??

for example, one bottle with filling hight inside is 1000mm, then

the zero hight is 1000mm, the reference is pgh.

So whether to give value in MPa or Pa?? And can u justify the use of hydrostatic loading on the diaphragm and what zero pressure height and reference pressure means in axisymmetric model??
