The M2D Time Control dialog allows the user to specify the starting day and time for the simulation.
Other options include:
Start Time: The hour at which to begin the model. This will be the first time step listed in any solution files.
Simulation Duration: The length of the simulation in hours.
Ramp Duration: The period of time in days at which to allow the model to “build up” or “ramp up” to a legitimate solution. Aids in the convergence of the model.
Time Step Size: The time increment at which M2D makes internal calculations. Running the M2D Model Check from the M2D menu will provide an initial estimation for the maximum time step size that will produce a convergent result.
