Smaller time step size is required
Did you know?
WebbSimulink. Fixed-step solvers solve the model at regular time intervals from the beginning to the end of the simulation. The size of the interval is known as the step size. You can specify the step size or let the solver choose the step size. Generally, a smaller the step size increases the accuracy of the results but also increases the time ... Webb21 mars 2009 · (del t = time step, del x = smallest mesh size, v = velocity) so if you have the minimum mesh size as 1mm, and velocity as 2 m/s, then your time step should be lower than 1mm/(2m/s) = 0.0005 sec. Any value higher than this may lead to divergence. Number of time steps depend on how long you want to run the simulation (flow time required)

WebbIn fact, it is this aspect of an implicit method that makes it attractive for steady-state computations, because the number of iterations required for a solution is often much smaller than the number of time steps needed for an accurate transient that asymptotically approaches steady conditions. popular cafe ravenshoeWebbA value of +9 indicates a step distance of 1 gu and dynamic step size reduction with CV = 1/9. A value of 109 indicates a step distance of 1/ (1 + abs (109-100)) = 0.1 gu and dynamic step size reduction with CV = 1/9.
