MeshModifiers

The MeshModifiers system is designed to modify the MooseMesh during the simulation.

note

Please let us know on GitHub Discussions how you are using the MeshModifiers system so we can include your techniques on this page!

Available Objects

Moose App
ActivateElementsByPathDetermine activated elements.
ActivateElementsCoupledDetermine activated elements.
CoupledVarThresholdElementSubdomainModifierModify the element subdomain ID if a coupled variable satisfies the criterion for the threshold (above, equal, or below)
SidesetAroundSubdomainUpdaterSets up a boundary between inner_subdomains and outer_subdomains
TimedSubdomainModifierModify element subdomain ID of entire subdomains for given points in time. This mesh modifier only runs on the undisplaced mesh, and it will modify both the undisplaced and the displaced mesh.
VariableValueElementSubdomainModifierModify the element subdomain ID based on the provided variable value.
