Module contents

discrete1.

Top-level package for the discrete1 library.

This package exports a small convenience API for creating spatial/energy/ angular grids and accessing material definitions. Importing the package will expose commonly-used helpers so downstream code can do:

import discrete1

to have access to the main functionality.

class discrete1.AngularData(angle_x: ndarray, angle_w: ndarray, P: ndarray | None = None, P_weights: ndarray | None = None)

Bases: object

Container for angular quadrature and optional Legendre data.

P: ndarray | None = None

P_weights: ndarray | None = None

angle_w: ndarray

angle_x: ndarray

class discrete1.Geometry(value)

Bases: IntEnum

Supported one-dimensional transport geometries.
