how many cycle should i put for iteration?
 
Hi All,

Anybody here can give some advice on iterations cycle? How to define that the numbers that i put for iteration is stabile?

thank you

You can use default number (100) for steady-state. If you don't get convergence after 150-200 iterations you should decrease a timescale or/and improve your mesh. Good luck!

Or increase your timescale. It depends on what is holding it up.

I think 10 is a good number! I used to put 20 for transient analysis!
