Detailed Description

This boundary condition provides a free-stream condition for pressure.

It is an outlet-inlet condition that uses the velocity orientation to continuously blend between zero gradient for normal inlet and fixed value for normal outlet flow.

Usage
Property Description Required Default value
U velocity field name no U
freestreamValue freestream pressure yes

Example of the boundary condition specification: 

    <patchName>
    {
        type            freestreamPressure;
        freestreamValue uniform 1e5;
    }
Note
This condition is designed to operate with a freestreamVelocity condition
