sarkas.particles.Particles.random_unit_vectors

Particles.random_unit_vectors(num_ptcls, dimensions)

Initialize random unit vectors for particles’ velocities (e.g. for monochromatic energies but random velocities). It calls numpy.random.Generator.normal().

Parameters

• num_ptcls (int) – Number of particles to initialize.

• dimensions (int) – Number of non-zero dimensions.

Returns

uvec (numpy.ndarray) – Random unit vectors of specified dimensions for all particles
