Is it possible to define a hydrostatic pressure(rho*g*h) on to a under water vehicle using EFD?

why?

When the underwater vehicle moving at a velocity(v) there will be variable pressure which is developed due weight of water which is acting on a body. Hw do you consider this using EFD?

I imaging that your vehicle must be deep.

Can you create a new fluid (based on water) to set the viscosity for each depth (pressure) that you want to examine? In the current engineering database the parameters are only functions of temperature. Why won't this work?
