SCMDetailedQuadSubChannelMeshGenerator
Creates a detailed mesh of subchannels 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 subchannels 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. The center of the mesh is the origin. Last the "side_gap" is an added distance between a perimetric pin and the duct, such that: distance(edge/corner pin center, duct wall) = pitch / 2 + side_gap.
Note that:
the vector (in the XY plane) from a corner pin center to the corner subchannel centroid is .
the vector (in the XY plane) from a corner pin center to the corner of the duct is .
Figure 1 presents a sketch of the SCM geometry nomenclature near the duct corner.
