DMSwarmInitializeVelocities

Set the initial velocities of particles using a distribution.

Synopsis

#include "petscdmswarm.h"   
PetscErrorCode DMSwarmInitializeVelocities(DM sw, PetscProbFn *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.
