- first_dtInitial time step (in absolute time)
C++ Type:double
Controllable:No
Description:Initial time step (in absolute time)
- log_dtTime step in log10(time)
C++ Type:double
Controllable:No
Description:Time step in log10(time)
LogConstantDT
Sets the time step so that it is constant in the logarithmic space. The initial time step must be set up independently.
TimeStepper which imposes a time step constant in the logarithmic space
Input Parameters
- cutback_factor_at_failure0.5Factor to apply to timestep if a time step fails to converge.
Default:0.5
C++ Type:double
Controllable:No
Description:Factor to apply to timestep if a time step fails to converge.
- growth_factor2Maximum ratio of new to previous timestep sizes following a step that required the time step to be cut due to a failed solve.
Default:2
C++ Type:double
Controllable:No
Description:Maximum ratio of new to previous timestep sizes following a step that required the time step to be cut due to a failed solve.
- reset_dtFalseUse when restarting a calculation to force a change in dt.
Default:False
C++ Type:bool
Controllable:No
Description:Use when restarting a calculation to force a change in dt.
Optional Parameters

C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTruewhether or not to enable the time stepper
Default:True
C++ Type:bool
