PatternedMeshGenerator

Creates a 2D mesh from a specified set of unique 'tiles' meshes and a two-dimensional pattern.

Overview

The PatternedMeshGenerator object is similar to TiledMeshGenerator. However, it is restricted to two dimensions and adds the ability to create a tile pattern from an arbitrary number of input meshes.

For example the input meshes shown in Figures 1 and 2 can be organized into a two dimensional pattern within the input file, as shown below, to create the pattern shown in Figure 3.
