openmc.examples.random_ray_three_region_cube_with_detectors() → Model

Create a three region cube model with two external tally regions.

This is an adaptation of the simple monoenergetic problem of a cube with three concentric cubic regions. The innermost region is near void (with Sigma_t around 10^-5) and contains an external isotropic source term, the middle region is a mild scatterer (with Sigma_t around 10^-3), and the outer region of the cube is a scatterer and absorber (with Sigma_t around 1).

Two cubic “detector” regions are found outside this geometry, one along the y-axis near z=0, and the other in the upper right corner of the system. The size of each detector is scaled to be equal to that of the source region. The model returned by this function contains cell tallies on each detector.

Added in version 0.16.0.

Returns:

model – A three region cube model

Return type:

openmc.Model
