Foam::fv::meanVelocityForce
Description
Creates a pressure gradient source
Calculates and applies the force necessary to maintain the specified mean
velocity.
Note: Currently only handles kinematic pressure
Note: Currently only handles kinematic pressure (incompressible solvers).
\heading Source usage
Example usage:
\verbatim
meanVelocityForceCoeffs
{
fieldNames (U); // name of velocity field
Ubar (10.0 0 0); // desired average velocity
gradPini gradPini [0 2 -2 0 0] 0; // initial pressure gradient
flowDir (1 0 0); // flow direction
fieldNames (U); // Name of velocity field
Ubar (10.0 0 0); // Desired mean velocity
relaxation 0.2; // Optional relaxation factor
