TiledMeshGenerator

Use the supplied mesh and create a tiled grid by repeating this mesh in the x, y, and z directions.

Example

As the name suggests, the TiledMeshGenerator object may be utilized to repeat a mesh multiple times. The test, tiled_mesh_generator.i, will be used to illustrate the use of the TiledMeshGenerator object. This test file is shown at the bottom of this section for reference.

Fig. 2: Tiled cube created from the cube input.

Fig. 1: Cube utilized as input to TiledMesh object.

The example utilizes a cube (cube.e) mesh as input as shown in Figure 1, which is a regular cube on the domain from 0 to 10 in the x, y, and z-directions.

As specified in the input file for this test (see below), this mesh is then used to create two tiles in the x, y, and z directions. To execute the example and create a new mesh, the moose test application can be executed with the special "–mesh-only" flag, which indicates that only the mesh operations should be performed. Running this command will create the resulting mesh file (tiled_mesh_test_in.e), which is intended to be used by a separate input file to run a complete simulation.
