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.
