TimeStepper System

The method used to calculate the size of the time steps is controlled by the TimeStepper block. There are a number of types of TimeStepper available, each of which controls the time stepping in different ways, including using fixed time stepping, time stepping based on a function, or adaptive time stepping.

• AB2PredictorCorrector
• CSVTimeSequenceStepperSolves the Transient problem at a sequence of given time points read in a file.
• ConstantDTTimestepper that takes a constant time step size
• DT2
• ExodusTimeSequenceStepperSolves the Transient problem at a sequence of time points taken from a specified exodus file.
• FunctionDTTimestepper whose steps vary over time according to a user-defined fuction
• IterationAdaptiveDTAdjust the timestep based on the number of iterations
• LogConstantDTTimeStepper which imposes a time step constant in the logarithmic space
• PostprocessorDT
• SolutionTimeAdaptiveDT
• TimeSequenceStepperSolves the Transient problem at a sequence of given time points.
