Hi everyone,

I have a general idea of CFX time stepping which I got from different sources. I hope someone can clarify some of my doubts regarding the subject.

1. I know that Min Coeff. Loop and Max Coeff. Loop are the number of iterations for each time step. If I specify Max Coeff. Loop to be 5 (random example), what happens if the convergence criteria is not met within those 5 iterations? What is an ideal value for Min Coeff. Loop and Max Coeff. Loop?

2. What is a good way to define a correct total time and time step size? I generally use a total time between 5 and 10 seconds, with a time step size of 2.5E-2. My idea is that the best result is produced with a large total time and a small time step size. Is this correct?

Thank you
