ReactorMeshParams

This ReactorMeshParams object acts as storage for persistent information about the reactor geometry.

Overview

The ReactorMeshParams object stores persistent mesh information about a reactor's geometry for use with PinMeshGenerator, AssemblyMeshGenerator, and CoreMeshGenerator. This is where the geometry type ("geom" as 'Square' or 'Hex' for cartesian and hexagonal definitions respectively) and the number of dimensions of the mesh ("dim" 2 or 3D) is declared and persistently enforced for the rest of the mesh definition. If the mesh is to be 3-dimensional, this is also where the axial information is declared ("axial_regions" and "axial_mesh_intervals").

  top_boundary_id = 201
  bottom_boundary_id = 202
