The CMS-Flow 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 CMS-Flow Model Check from the CMS-Flow menu will provide an initial estimation for the maximum time step size that will produce a convergent result.
