Reply To: hydrostatic pressure vs pressure

[peteroznewman]

To model the experiment where water pressure was increased from 0 to 15 MPa in Ansys, just use Pressure, which will put the same load over the surfaces selected in your model.

Do not use Hydrostatic Pressure, which assumes that only the weight of the water, pulled down by gravity has a pressure that starts at 0 at the free surface and increases linearly with depth below the free surface. That is not what you have in this experiment.
