StitchedMeshGenerator

!syntax description /Mesh/StitchedMeshGenerator

Example

Consider the following three meshes.

!media media/mesh/stitched_mesh_left.png style=width:32%;float:left; caption=Fig. 1: Left portion of "stitched" mesh (left.e).

!media media/mesh/stitched_mesh_center.png style=width:32%;float:left;margin-left:2%; caption=Fig. 2: Center portion of "stitched" mesh (center.e).

!media media/mesh/stitched_mesh_right.png style=width:32%;float:right; caption=Fig. 3: Right portion of "stitched" mesh (right.e).

Using the StitchedMeshGenerator object from within the Mesh block of the input file, as shown in the input file snippet below, these three square meshes are joined into a single mesh as shown in Figure 4.

Note that the way that the meshes are merged gives precedence to the left-most mesh listed in terms of sidesets: the sidesets of the second, third, etc meshes will be subsumed into the sidesets of the first mesh. The names of the sidesets in the first mesh are what the names that will remain in the outputted mesh.
