the max iteration numbers in one time step
 

solving unsteady flow, there is a max itration numbers in one time step. what's meanning. whether or not the solution will turn to next time step if it couldn't reach a convergence solution for max iteration numbers in this time step. if i want to reach a convergence solution for every time step, what shall i do? thanks

Hello,

You could increase the number of max iteration in one time step to an important value like for example 100000.

is that the only way? thanks

Best thing is to reduce time step size until the residuals drop by two-three orders of magnitude in 5-10 iterations per time step.
