Detailed Description

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

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


Source usage Example usage:

patchMeanVelocityForceCoeffs
{
    selectionMode   all;                    // Apply force to all cells
    fieldNames      (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
