DMSwarmInitializeVelocities#
Set the initial velocities of particles using a distribution.
Synopsis#
#include "petscdmswarm.h"
PetscErrorCode DMSwarmInitializeVelocities(DM sw, PetscProbFunc sampler, const PetscReal v0[])
Collective on dm
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.
