StitchedMeshGenerator

Allows multiple mesh files to be stiched together to form a single mesh.

Example

Consider the following three meshes.

Fig. 1: Left portion of "stitched" mesh (left.e).

Fig. 2: Center portion of "stitched" mesh (center.e).

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.

[Mesh]
  [./fmg_left]
    type = FileMeshGenerator
    file = left.e
  []

  [./fmg_center]
    type = FileMeshGenerator
    file = center.e
  []

  [./fmg_right]
    type = FileMeshGenerator
    file = right.e
  []

  [./smg]
    type = StitchedMeshGenerator
    inputs = 'fmg_left fmg_center fmg_right'
    clear_stitched_boundary_ids = true
    stitch_boundaries_pairs = 'right left;
                               right left'
    parallel_type = 'replicated'
