DMSwarmInitializeVelocities#

Set the initial velocities of particles using a distribution.

Synopsis#

#include "petscdmswarm.h"   
PetscErrorCode DMSwarmInitializeVelocities(DM sw, PetscProbFunc sampler, const PetscReal v0[])

Collective

Input Parameters#

  • sw - The DMSWARM object

  • sampler - A function which uniformly samples the velocity PDF

  • v0 - The velocity scale for nondimensionalization for each species

Note#

If v0 is zero for the first species, all velocities are set to zero. If it is zero for any other species, the effect will be to give that species zero velocity.
