SCMDetailedQuadPinMeshGenerator

Creates a detailed mesh of fuel pins in a square lattice arrangement

Overview

This is a mesh generator used for visualization purposes only. It is part of an input file that creates a 3D realistic mesh of the pins in a square lattice arrangement. This input file has a Problem block with the NoSolveProblem because it is not used to perform any calculations. It is used to create a detailed 3D mesh that the SCM solution gets projected on. Last, "input" is a parameter that takes the name of an object of type SCMDetailedQuadSubChannelMeshGenerator so the user must be careful to define consistent parameters across both MeshGenerators. The center of the mesh is the origin.
