In ansys fluent, there are two options available for time step method under pseudo time settings:
1. Automatic
2. User-specified

For automatic time step method [1], time scale factor and length scale method is allowed to adjust.
From my understanding, length scale method is to adjust the way to calculate the characteristics length of the domain. Verbosity is just to controls the amount of information printed to the console or log files during the simulation.


For user-specified method [2], user is free to adjust any time length (in seconds) for pseudo time step size.


Does anyone can explain how fluent calculate pseudo time length based on the given time scale factor automatically ?
Is there any method to observe the results of pseudo time step size (in second) under auto-mode for all the itarations?
Does number of iterations affected by time scale factor set ? If yes, then how ?

Let me know if anything unclear or wrong description.
