Detailed Description

Crank-Nicolson 2nd-order time-integrator for 6DoF solid-body motion.

The off-centering coefficients for acceleration (velocity integration) and velocity (position/orientation integration) may be specified but default values of 0.5 for each are used if they are not specified. With the default off-centering this scheme is equivalent to the Newmark scheme with default coefficients.

Example specification in dynamicMeshDict:

solver
{
    type    CrankNicolson;
    aoc     0.5;    // Acceleration off-centering coefficient
    voc     0.5;    // Velocity off-centering coefficient
}
