pressureDirectedInletOutletVelocityFvPatchVectorField Class Reference

This velocity inlet/outlet boundary condition is applied to velocity boundaries 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 the specified inlet direction. More...

Detailed Description

This velocity inlet/outlet boundary condition is applied to velocity boundaries 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 the specified inlet direction.

Usage

Property	Description	Required	Default value
phi	flux field name	no	phi
rho	density field name	no	rho
inletDirection	inlet direction per patch face	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            pressureDirectedInletOutletVelocity;
        phi             phi;
        rho             rho;
        inletDirection  uniform (1 0 0);
        value           uniform 0;
    }

Note

Sign conventions:

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