Fluent absolute pressure limited to 1
WebSince you have set the operating pressure to zero, you will specify the boundary condition inputs for pressure in terms of absolute pressures when you define them in the next step. Boundary condition inputs for pressure should always be relative to the value used for operating pressure. 6.4.7. Creating the Boundary Conditions 1.
