class picmistandard.PICMI_GriddedLayout(n_macroparticles_per_cell=None, grid=None, **kw)[source]

Specifies a gridded layout of particles

Parameters:

n_macroparticle_per_cell (vector of integers) – Number of particles per cell along each axis
grid (grid instance, optional) – Grid object specifying the grid to follow. If not specified, the underlying grid of the code is used.

class picmistandard.PICMI_PseudoRandomLayout(n_macroparticles=None, n_macroparticles_per_cell=None, seed=None, grid=None, **kw)[source]

Specifies a pseudo-random layout of the particles

Parameters:

n_macroparticles (integer) – Total number of macroparticles to load. Either this argument or n_macroparticles_per_cell should be supplied.
n_macroparticles_per_cell (integer) – Number of macroparticles to load per cell. Either this argument or n_macroparticles should be supplied.
seed (integer, optional) – Pseudo-random number generator seed
grid (grid instance, optional) – Grid object specifying the grid to follow for n_macroparticles_per_cell. If not specified, the underlying grid of the code is used.
