pressureInletOutletVelocityFvPatchVectorField 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 patch-face normal component of the internal-cell value. 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 patch-face normal component of the internal-cell value.

The tangential patch velocity can be optionally specified.


Patch usage

Property Description Required Default value
phi flux field name no phi
tangentialVelocity tangential velocity field no

Example of the boundary condition specification:

    myPatch
    {
        type            pressureInletOutletVelocity;
        phi             phi;
        tangentialVelocity uniform (0 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 in the patch-normal direction
