This fvOption applies an explicit damping force to components of the
vector field in the direction of gravity. Its intended purpose is to
damp the vertical motions of an interface in the region approaching an
outlet so that no reflections are generated. The level of damping is
specified by a coefficient, lambda, given in units of 1/s.
It can be enabled for a cellZone named "nearOutlet", by adding the
following entry to constant/fvOptions:
verticalDamping1
{
type verticalDamping;
selectionMode cellZone;
cellZone nearOutlet;
lambda [0 0 -1 0 0 0 0] 1;
timeStart 0;
duration 1e6;
}

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
