    ABAQUS - Load Module, Pressure

    hi, I'm 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 i'm 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??

  2. #2
    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??
