C++ Type:std::vector<MeshGeneratorName>
Controllable:No
Description:The input MeshGenerators. This can either be N generators or 1 generator. If only 1 is given then 'positions' must also be given.
CombinerGenerator
Combine multiple meshes (or copies of one mesh) together into one (disjoint) mesh. Can optionally translate those meshes before combining them.
Overview
The CombinerGenerator allows the user to combine the outputs of multiple MeshGenerators into a single mesh. This is somewhat similar to the StitchedMeshGenerator with the difference being that CombinerGenerator makes no attempt to "heal" / "join" the mesh like StitchedMeshGenerator does. There CombinerGenerator is more suited to creation of disjoint meshes (where the individual pieces are not directly tied together).
commentnote:Mesh naming precedence
CombinerGenerator preserves subdomain names and boundary names (node sets, side sets, and edge sets). If the corresponding IDs exist in multiple meshes, then the meshes/copies listed later in "inputs"/"positions" take precedence.
Usage
There are three main ways to use the CombinerGenerator:
1. Combine Multiple MeshGenerators
The most straightforward thing to do is simply to combine the output of multiple MeshGenerators together into a single mesh. For example:
[Mesh]
[gen1]
type = GeneratedMeshGenerator
dim = 2
nx = 10
ny = 10
xmin = 0
xmax = 1
ymin = 0
ymax = 1
[]
[gen2]
type = GeneratedMeshGenerator
dim = 2
nx = 12
ny = 12
xmin = 2
xmax = 3
ymin = 2
ymax = 3
[]
[gen3]
type = GeneratedMeshGenerator
dim = 2
nx = 14
ny = 14
xmin = 3.5
xmax = 5
ymin = 3
ymax = 4
[]
[cmbn]
type = CombinerGenerator
inputs = 'gen1 gen2 gen3'
[]
[]
Will generate a mesh that looks like:
2. Combine Multiple MeshGenerators AND Translate Them
It is also possible to translate (move) the input MeshGenerators as they are combined. This is done using the positions option which takes triplets of floating point numbers that are interpreted as displacement vectors for moving each of the input meshes.
commentnote
If you specify positions then the number of positions must match the number of inputs, unless only one input is specified (more on that in a moment).
[Mesh]
[gen1]
type = GeneratedMeshGenerator
dim = 2
nx = 10
ny = 10
[]
[gen2]
type = GeneratedMeshGenerator
dim = 2
nx = 12
ny = 12
[]
[gen3]
type = GeneratedMeshGenerator
dim = 2
nx = 14
ny = 14
[]
[cmbn]
type = CombinerGenerator
inputs = 'gen1 gen2 gen3'
positions = '1 0 0 2 2 2 3 0 0'
[]
[]
Will generate a mesh that looks like:
Alternatively, the same displacement vectors can be supplied in a file with the positions_file option. The above mesh can equivalently be generated with the following.
[Mesh]
[gen1]
type = GeneratedMeshGenerator
dim = 2
nx = 10
ny = 10
[]
[gen2]
type = GeneratedMeshGenerator
dim = 2
nx = 12
ny = 12
[]
[gen3]
type = GeneratedMeshGenerator
dim = 2
nx = 14
ny = 14
[]
[cmbn]
type = CombinerGenerator
inputs = 'gen1 gen2 gen3'
positions_file = 'positions.txt'
[]
[]
where the positions.txt file contains the floating point triplets.
1 0 0
2 2 2
3 0 0
The same restrictions on positions also apply to the number of entries in position_file.
3. Copy a Single Input Multiple Times With Translations
The final option is to provide exactly one inputs but specify multiple positions. This will cause the single input to be copied multiple times with the position of each copy specified by the positions parameter. For example
[Mesh]
[gen]
type = GeneratedMeshGenerator
dim = 2
nx = 10
ny = 10
[]
[cmbn]
type = CombinerGenerator
inputs = 'gen'
positions = '1 0 0 2 2 2 3 0 0'
[]
[]
Will generate a mesh that looks like:
Again, the same capability can be achieved with the positions_file option.

# This input file tests MooseMesh::getBlocksMaxDimension(), which gets the MESH
# dimension of a list of subdomain names.
#
# Note the differences between the MESH dimension and the SPATIAL dimension.
# The SPATIAL dimension just looks at the maximum coordinate dimension used:
# - Equals 3 if there is a nonzero z coordinate
# - Equals 2 if there is no nonzero z coordinate, but there is a nonzero y coordinate
# - Equals 1 if there is no nonzero y or z coordinate
# In contrast, the MESH dimension looks at the dimensionality of the elements.
# Therefore, the MESH dimension differs from the SPATIAL dimension when:
# - a 1D element has a nonzero y or z coordinate
# - a 2D element has a nonzero z coordinate
# This test will include subdomains with these cases and test different
# lists of subdomains.
