Detailed Description

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

Usage

Example usage:

patchMeanVelocityForce1
{
    type            patchMeanVelocityForce;

    selectionMode   all;

    U               U;          // Name of velocity field

    patch           inlet;      // Name of the patch

    Ubar            (10.0 0 0); // Desired mean velocity
    relaxation      0.2;        // Optional relaxation factor
   }

Note: Currently only handles kinematic pressure (incompressible solvers).
