Hi I’m user of graduated student.
I have some question for this model,
I want to know how to calculate the Time Step in EFDC source code.
I wonder that CFL number is calculated in this process such as
(\delta x * u)/\delta t + (\delta y * u)/\delta t + (\delta z * u)/\delta t < 1
but I calculated it with hand, it is quite different with EFDC time step CFL number.
i have a very simple gird that x, y, z is 100m20m1m
and grid size is 2m1m (grid number 5020)
and when i calculated it with my hand to use that equation, i got 1500s
but in the efdc model, that suggest 0.14s CFL number.
how i supposed to know that time step in EFDC?
please answer me.
