to provide smoother behavior on start-up when an acceleration impulse is
applied, e.g. if the body is suddenly released. e.g.

will quadratically ramp the forces from 0 to their full values over the first
10s of the run starting from 0. If the 'ramp' entry is omitted no force ramping
is applied.

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.
