PatternedMesh
Creates a 2D mesh from a specified set of unique 'tiles' meshes and a two-dimensional pattern.
The PatternedMesh object is similar to TiledMesh but restricted to two dimensions but 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.

- up_directionSpecify what axis corresponds to the up direction in physical space (the opposite of the gravity vector if you will).

If you want finer grained control than this, please use the 'alpha_rotation', 'beta_rotation', and 'gamma_rotation' parameters.
