FancyExtruderGenerator

Extrudes a 2D mesh into 3D, can have variable a variable height for each elevation, variable number of layers within each elevation and remap subdomain_ids within each elevation

Overview

The FancyExtruderGenerator adds more customization options over the MeshExtruderGenerator.

Input Parameters

directionA vector that points in the direction to extrude (note, this will be normalized internally - so don't worry about it here)
C++ Type:libMesh::Point
Options:
Description:A vector that points in the direction to extrude (note, this will be normalized internally - so don't worry about it here)
heightsThe height of each elevation
C++ Type:std::vector<double>
Options:
Description:The height of each elevation
inputThe mesh to extrude
C++ Type:MeshGeneratorName
Options:
Description:The mesh to extrude
num_layersThe number of layers for each elevation - must be num_elevations in length!
C++ Type:std::vector<unsigned int>
Options:
Description:The number of layers for each elevation - must be num_elevations in length!

Required Parameters

bottom_boundaryThe boundary ID to set on the bottom boundary. If omitted one will be generated.
C++ Type:short
Options:
Description:The boundary ID to set on the bottom boundary. If omitted one will be generated.
show_infoFalseWhether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Default:False
C++ Type:bool
Options:
Description:Whether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
subdomain_swapsFor each row, every two entries are interpreted as a pair of 'from' and 'to' to remap the subdomains for that elevation
C++ Type:std::vector<std::vector<unsigned short>>
Options:
Description:For each row, every two entries are interpreted as a pair of 'from' and 'to' to remap the subdomains for that elevation
top_boundaryThe boundary ID to set on the top boundary. If ommitted one will be generated.
C++ Type:short
Options:
Description:The boundary ID to set on the top boundary. If ommitted one will be generated.

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Options:
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Options:
Description:Set the enabled status of the MooseObject.
