Setting up static pressure
Hi everyone, I'm relatively new to using CFX and I need some assistance with setting up the static pressure in the fluid domain.
I want to set the static pressure of my domain to that of the underwater pressure, ie. Atmospheric + rho*g*z where the variable in this equation is z. So my question is, where do I key in this equation? Is it under initialization>static pressure>relative pressure? Any help is greatly appreciated. Thanks |
First, create an expression “main menu->insert->expression”, and then use it in the domain initialization.

Abou describes how to add an equation.
But my question is why do you want to do this? If you read the documentation you will find in a buoyant simulation the pressure variable already have the hydrostatic component removed from it. The absolute pressure contains the hydrostatic component (and the reference pressure offset). |
