Hydrodynamic pressures in AQWA... more like hydro-dumb-namic pressures?
I am simulating a simple cylinder in regular waves (frequency domain) in AQWA - Hydrodynamic Diffraction. Here's a picture of the resulting pressures around the body:
The step on pressures on the free surface doesn't seem right. It also doesn't make sense to me that the largest hydrodynamic pressures are on the free surface... I mean, yes, wave action is larger there, but aren't hydrostatic pressures also included in this value, thus, increasing pressures on the bottom?
Any insight is appreciated :)
