◆ MaxRMSDisplacementFac

double timestep_params::MaxRMSDisplacementFac

this determines a global timestep criterion for cosmological simulations in comoving coordinates. To this end, the code computes the rms velocity of all particles, and limits the timestep such that the rms displacement is a fraction of the mean particle separation (determined from the particle mass and the cosmological parameters). This parameter specifies this fraction.
