CartesianMeshGenerator
This CartesianMeshGenerator creates a non-uniform Cartesian mesh.
Overview
The CartesianMeshGenerator object is the built-in mesh generation capable of creating lines, rectangles, and hexahedra ("boxes"). The mesh spacing can be non-uniform and each line/rectangle/hexahedron can be assigned a separate subdomain id. The mesh automatically creates side sets that are logically named and numbered as follows:
In 1D, left = 0, right = 1
In 2D, bottom = 0, right = 1, top = 2, left = 3
In 3D, back = 0, bottom = 1, right = 2, top = 3, left = 4, front = 5
The length, width, and height of each element, as well as their subdomain id can be set independently. Each linear subdivision in x, y, or z can be additionally subdivided into sub-elements.
