time step and iteration
 
Hi, I am a beginner in ANSYS FLUENT

May I ask, what is the difference between time step and iteration?

Thanks a lot.

Hi,
the time step is the delta time of the simulation, which corresponds to the real time.
Iteration is a cycle to reach a solution; in fact you can have multiple iterations per time step.
