pressureNormalInletOutletVelocityFvPatchVectorField Class Reference

This velocity inlet/outlet boundary condition is applied to patches where the pressure is specified. A zero-gradient condition is applied for outflow (as defined by the flux); for inflow, the velocity is obtained from the flux with a direction normal to the patch faces. More...

Detailed Description

This velocity inlet/outlet boundary condition is applied to patches where the pressure is specified. A zero-gradient condition is applied for outflow (as defined by the flux); for inflow, the velocity is obtained from the flux with a direction normal to the patch faces.

Usage

Property	Description	Required	Default value
phi	flux field name	no	phi
rho	density field name	no	rho

Example of the boundary condition specification:

    <patchName>
    {
        type            pressureNormalInletOutletVelocity;
        phi             phi;
        rho             rho;
        value           uniform 0;
    }

Note: Sign conventions:

• positive flux (out of domain): apply zero-gradient condition
• negative flux (into of domain): derive from the flux and patch-normal direction
