MultiAppCopyTransfer

The MultiAppCopyTransfer allows for copying variables (both nonlinear and auxiliary) between MultiApps. All types of variables, including higher order, elemental, and nodal are supported. The only limitation is that the meshes in the master and sub application must be identical.

Input Parameters

directionWhether this Transfer will be 'to' or 'from' a MultiApp, or bidirectional, by providing both FROM_MULTIAPP and TO_MULTIAPP.
C++ Type:MultiMooseEnum
Options:to_multiapp from_multiapp
Description:Whether this Transfer will be 'to' or 'from' a MultiApp, or bidirectional, by providing both FROM_MULTIAPP and TO_MULTIAPP.
multi_appThe name of the MultiApp to use.
C++ Type:MultiAppName
Options:
Description:The name of the MultiApp to use.
source_variableThe variable to transfer from.
C++ Type:std::vector
Options:
Description:The variable to transfer from.
variableThe auxiliary variable to store the transferred values in.
C++ Type:std::vector
Options:
Description:The auxiliary variable to store the transferred values in.

Required Parameters

check_multiapp_execute_onTrueWhen false the check between the multiapp and transfer execute on flags is not preformed.
Default:True
C++ Type:bool
Options:
Description:When false the check between the multiapp and transfer execute on flags is not preformed.
displaced_source_meshFalseWhether or not to use the displaced mesh for the source mesh.
Default:False
C++ Type:bool
Options:
Description:Whether or not to use the displaced mesh for the source mesh.
displaced_target_meshFalseWhether or not to use the displaced mesh for the target mesh.
Default:False
C++ Type:bool
Options:
Description:Whether or not to use the displaced mesh for the target mesh.
execute_onSAME_AS_MULTIAPPThe list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM, SAME_AS_MULTIAPP.
Default:SAME_AS_MULTIAPP
C++ Type:ExecFlagEnum
Options:NONE INITIAL LINEAR NONLINEAR TIMESTEP_END TIMESTEP_BEGIN FINAL CUSTOM SAME_AS_MULTIAPP

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.
use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
Default:False
C++ Type:bool
Options:
Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
