Module Contents

class picongpu.pypicongpu.grid.BoundaryCondition(*args, **kwds)

Bases: enum.Enum

Boundary Condition of PIConGPU

Defines how particles that pass the simulation bounding box are treated.

TODO: implement the other methods supported by PIConGPU (reflecting, thermal)

PERIODIC = 1

ABSORBING = 2

get_cfg_str() → str

Get string equivalent for cfg files :return: string for –periodic

class picongpu.pypicongpu.grid.Grid3D

Bases: picongpu.pypicongpu.rendering.RenderedObject

PIConGPU 3 dimensional (cartesian) grid

Defined by the dimensions of each cell and the number of cells per axis.

The bounding box is implicitly given as TODO.

cell_size_x_si

Width of individual cell in X direction

cell_size_y_si

Width of individual cell in Y direction

cell_size_z_si

Width of individual cell in Z direction

cell_cnt_x

total number of cells in X direction

cell_cnt_y

total number of cells in Y direction

cell_cnt_z

total number of cells in Z direction

boundary_condition_x

behavior towards particles crossing the X boundary

boundary_condition_y

behavior towards particles crossing the Y boundary

boundary_condition_z

behavior towards particles crossing the Z boundary

n_gpus

number of GPUs in x y and z direction as 3-integer tuple

__hash__()

custom hash function for indexing in dicts

get_rendering_context() → dict | None

get rendering context representation of this object

delegates work to _get_serialized and invokes checks performed by check_context_for_type(). :raise ValidationError: on schema violation :raise RuntimeError: on schema not found :return: self as rendering context

static check_context_for_type(type_to_check: type, context: dict | None) → None

check if the given context is valid for the given type

Raises on error, passes silently if okay.

Raises:

• ValidationError – on schema violation

• RuntimeError – on schema not found
