freestreamPressureFvPatchScalarField Class Reference

This boundary condition provides a free-stream condition for pressure. It is a zero-gradient condition that constrains the flux across the patch based on the free-stream velocity. More...

Detailed Description

This boundary condition provides a free-stream condition for pressure. It is a zero-gradient condition that constrains the flux across the patch based on the free-stream velocity.

Patch usage

Property	Description	Required	Default value
U	velocity field name	no	U
phi	flux field name	no	phi
rho	density field name	no	none

Example of the boundary condition specification:

    myPatch
    {
        type            freestreamPressure;
    }

Note

This condition is designed to operate with a freestream velocity condition
