GeneratedMesh
Create a line, square, or cube mesh with uniformly spaced or biased elements.
Description
The GeneratedMesh object is the built-in mesh generation capable of creating lines, rectangles, and rectangular prisms ("boxes"). The mesh automatically creates side sets that are logically named and numbered as follows:
* In 1D, left = 0, right = 1 * In 2D, bottom = 0, right = 1, top = 2, left = 3 * In 3D, back = 0, bottom = 1, right = 2, top = 3, left = 4, front = 5
The length, width, and height of the domain, as well as the number of elements in each direction can be specified independently.
Example Syntax
[Mesh]
type = GeneratedMesh
dim = 2
nx = 10
ny = 10
[]Input Parameters
- partitionerdefaultSpecifies a mesh partitioner to use when splitting the mesh for a parallel computation.
Default:default
C++ Type:MooseEnum
Description:Specifies a mesh partitioner to use when splitting the mesh for a parallel computation.
- centroid_partitioner_directionSpecifies the sort direction if using the centroid partitioner. Available options: x, y, z, radial
C++ Type:MooseEnum
Description:Specifies the sort direction if using the centroid partitioner. Available options: x, y, z, radial
Partitioning Parameters
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Description:Set the enabled status of the MooseObject.
- patch_update_strategyneverHow often to update the geometric search 'patch'. The default is to never update it (which is the most efficient but could be a problem with lots of relative motion). 'always' will update the patch for all slave nodes at the beginning of every timestep which might be time consuming. 'auto' will attempt to determine at the start of which timesteps the patch for all slave nodes needs to be updated automatically.'iteration' updates the patch at every nonlinear iteration for a subset of slave nodes for which penetration is not detected. If there can be substantial relative motion between the master and slave surfaces during the nonlinear iterations within a timestep, it is advisable to use 'iteration' option to ensure accurate contact detection.
