- inputThe mesh we want to modify
C++ Type:MeshGeneratorName
Controllable:No
Description:The mesh we want to modify
- sidesetsThe sidesets from which to create the new block
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The sidesets from which to create the new block
LowerDBlockFromSidesetGenerator
Adds lower dimensional elements on the specified sidesets.
Overview
This mesh generator accepts a list of sidesets and creates a lower dimensional block of elements along those sides. The order of the newly create lower dimensional element block will match the order of the parent elements (e.g. first order for first order parents, second order for second order parents).
Input Parameters
- new_block_idThe lower dimensional block id to create
C++ Type:unsigned short
Controllable:No
Description:The lower dimensional block id to create
- new_block_nameThe lower dimensional block name to create (optional)
C++ Type:SubdomainName
Controllable:No
Description:The lower dimensional block name to create (optional)
- 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
Controllable:No
Description:Whether or not to show mesh info after generating the mesh (bounding box, element types, sidesets, nodesets, subdomains, etc)
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.

# A fracture, which is a 1D line of elements, is embedded in a matrix, which is a 2D surface of elements.
# The meshes conform: all fracture nodes are also matrix nodes (the fracture elements are sides of matrix elements).
# The overall mesh has two blocks, named "matrix" and "fracture".
#
# Two variables are defined:
# - frac_T, which is the temperature inside the fracture;
# - matrix_T, which is the temperature in the matrix.
# frac_T is governed by a diffusion equation along the 1D fracture.
# matrix_T is governed by a diffusion equation in the 2D matrix, with small diffusion coefficient.
# Heat is exchanged between the two systems via a heat-transfer coefficient, defined on the fracture subdomain, using two PorousFlowHeatMassTransfer Kernels
#
# If the mesh is too coarse, overshoots and undershoots in matrix_T can be observed.
