pressureDirectedInletOutletVelocityFvPatchVectorField Class Reference

This velocity inlet/outlet boundary condition is applied to pressure 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 pressure 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
