- boundaryThe list of boundary IDs from the mesh where this object applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundary IDs from the mesh where this object applies
- initial_load_capInitial cap of the loading. The load is decreased once it reaches the cap, the cap is then increased according to the load cap increment.
C++ Type:double
Controllable:No
Description:Initial cap of the loading. The load is decreased once it reaches the cap, the cap is then increased according to the load cap increment.
- load_cap_incrementThe amount to increase the load cap everytime it is reached.
C++ Type:double
Controllable:No
Description:The amount to increase the load cap everytime it is reached.
- load_stepThe amount to increase the load every step.
C++ Type:double
Controllable:No
Description:The amount to increase the load every step.
- ultimate_loadThe load, upon reached, to terminate the simulation.
C++ Type:double
Controllable:No
Description:The load, upon reached, to terminate the simulation.
- unloaded_indicatorA postprocessor whose value serves as an indicator for unloaded status. Once its value is below zero, the system is completely unloaded, and loading starts again.
C++ Type:PostprocessorName
Controllable:No
Description:A postprocessor whose value serves as an indicator for unloaded status. Once its value is below zero, the system is completely unloaded, and loading starts again.
- variableThe name of the variable that this residual object operates on
C++ Type:NonlinearVariableName
Controllable:No
Description:The name of the variable that this residual object operates on
LoadingUnloadingDirichletBC
This class applies a loading/unloading BC. The load ramps up linearly until it reaches the load cap. Once the load cap is reached, the load cap is incremented and unlading begins. Once the unloaded indicator becomes negative, loading starts. If the load cap exceeds the ultimate load, the entire loading/unloading terminates, and the current simulation is terminated.
