- inputThe mesh we want to modify
C++ Type:MeshGeneratorName
Description:The mesh we want to modify
- sidesetsThe sidesets from which to create the new block
C++ Type:std::vector
Description:The sidesets from which to create the new block
LowerDBlockFromSidesetGenerator
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.
Adds lower dimensional elements on the specified sidesets.
Input Parameters
- new_block_idThe lower dimensional block id to create
C++ Type:unsigned short
Options:
Description:The lower dimensional block id to create
- new_block_nameThe lower dimensional block name to create (optional)
C++ Type:SubdomainName
Options:
Description:The lower dimensional block name to create (optional)
Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
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.
