Off-centering is specified via the mandatory coefficient \c ocCoeff in the
range [0,1] following the scheme name e.g.
\verbatim
ddtSchemes
{
default CrankNicolson 0.9;
}
\endverbatim
or with an optional "ramp" function to transition from the Euler scheme to
Crank-Nicolson over a initial period to avoid start-up problems, e.g.
\verbatim
ddtSchemes
{
default CrankNicolson
ocCoeff
{
type scale;
scale linearRamp;
duration 0.01;
value 0.9;
};
}
\endverbatim
Note this functionality is experimental and the specification and implementation
may change if issues arise.

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.
