mcdc.MeshUniform#

class mcdc.MeshUniform(name: str = '', x: tuple[float, float, int] = (-10000000000.0, 20000000000.0, 1), y: tuple[float, float, int] = (-10000000000.0, 20000000000.0, 1), z: tuple[float, float, int] = (-10000000000.0, 20000000000.0, 1))#

Uniform spatial bins for simulation tallies and transport techniques.

Parameters:

  • name (str, optional) – User-facing mesh name.

  • x (tuple of (float, float, int), optional) – (origin, spacing, number_of_bins) for each axis, in cm. Omitted axes default to one effectively unbounded bin.

  • y (tuple of (float, float, int), optional) – (origin, spacing, number_of_bins) for each axis, in cm. Omitted axes default to one effectively unbounded bin.

  • z (tuple of (float, float, int), optional) – (origin, spacing, number_of_bins) for each axis, in cm. Omitted axes default to one effectively unbounded bin.

Examples

Create 100 uniform bins along z from 0 to 10 cm:

>>> import mcdc
>>> mesh = mcdc.MeshUniform(z=(0.0, 0.1, 100))

Create a two-dimensional x-y mesh:

>>> mesh_xy = mcdc.MeshUniform(
...     x=(-5.0, 0.5, 20),
...     y=(-5.0, 0.5, 20),
... )

Create a three-dimensional mesh with different axis spacings:

>>> mesh_xyz = mcdc.MeshUniform(
...     x=(0.0, 1.0, 10),
...     y=(0.0, 2.0, 5),
...     z=(-3.0, 0.25, 24),
... )
