I tried using the Hydrodynamics analysis in Mentat. You can give de cavitation pressure of the oil. But it seems it doesn't work. If I give 0 at the cavitation pressure the software shows me the negative pressures in the result. Please help.

I suppose everything is given in relative pressure. For example if I give 0 pressure at the boundary condition it is relative. But even if I give absolute pressure for the cavitation pressure nothing happens. In the documentation it writes if the pressure is below the cavitation pressure the software sets the cavitation pressure at the integration point. Does somebody have experience with this?

I found an answer. The system sets the cavitation pressure when it computes the nodal forces.
