mcdc.MeshStructured#

class mcdc.MeshStructured(name: str = '', x: Sequence[float] | ndarray[tuple[Any, ...], dtype[float64]] = array([-1.e+10, 1.e+10]), y: Sequence[float] | ndarray[tuple[Any, ...], dtype[float64]] = array([-1.e+10, 1.e+10]), z: Sequence[float] | ndarray[tuple[Any, ...], dtype[float64]] = array([-1.e+10, 1.e+10]))#

Structured spatial bins for simulation tallies and transport techniques.

Parameters:

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

  • x (sequence of float, optional) – Strictly ordered grid boundaries in cm. Each omitted axis defaults to one effectively unbounded bin.

  • y (sequence of float, optional) – Strictly ordered grid boundaries in cm. Each omitted axis defaults to one effectively unbounded bin.

  • z (sequence of float, optional) – Strictly ordered grid boundaries in cm. Each omitted axis defaults to one effectively unbounded bin.

Examples

Create nonuniform bins along z:

>>> import mcdc
>>> mesh = mcdc.MeshStructured(z=[0.0, 0.5, 2.0, 10.0])

Create a two-dimensional mesh from explicit boundaries:

>>> mesh_xy = mcdc.MeshStructured(
...     x=[-2.0, -1.0, 0.0, 2.0],
...     y=[-3.0, 0.0, 1.0, 3.0],
... )

Mix uniformly generated and explicitly listed boundaries:

>>> import numpy as np
>>> mesh_xyz = mcdc.MeshStructured(
...     x=np.linspace(-5.0, 5.0, 21),
...     y=[-1.0, 0.0, 1.0],
...     z=np.linspace(0.0, 10.0, 101),
... )
