Detailed Description

Calculates and applies the force necessary to maintain the specified mean velocity.

Usage
Example usage:
meanVelocityConstraint
{
    type            meanVelocityForce;

    selectionMode   all;

    U               U;          // Name of velocity field

    Ubar            (10.0 0 0); // Desired mean velocity
    relaxation      0.2;        // Optional relaxation factor
}
Note
Currently only handles kinematic pressure (incompressible solvers).
