Description:Vector of output names where you would like to restrict the output of variables(s) associated with this object
- 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
Controllable:No
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.
Advanced Parameters
- prop_getter_suffixAn optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
C++ Type:MaterialPropertyName
Unit:(no unit assumed)
Controllable:No
Description:An optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
- use_interpolated_stateFalseFor the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.
Default:False
C++ Type:bool
Controllable:No
Description:For the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.

# Tests HeatStructure2DCoupler when the heat structures are separated by some
# distance. The first heat structure has a larger coupling surface than the
# second heat structure. The component will be used to model a given energy
# transfer rate per unit temperature difference [W/K]. This test checks that:
# a) heat transfer occurs in the correct direction
# b) energy is conserved
#
# With a goal of transferring 5 W/K and a temperature difference of 200 K, and
# a transient time of 10 seconds, ~10 kJ should be transferred. Note that this
# estimate will not be exact since the temperature difference changes slightly
# over the transient.
