Detailed Description

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

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

Usage
Property Description Required Default value
freestreamValue freestream velocity yes

Example of the boundary condition specification: 

    <patchName>
    {
        type            freestreamVelocity;
        freestreamValue uniform (300 0 0);
    }
Note
This condition is designed to operate with the freestreamPressure condition
