Hi,

It's important to note that stopping the simulation early might affect the results, especially if the flow has not fully developed or reached a steady state by 20 seconds. In some cases, such as when dealing with high continuity residuals, it's suggested to reduce the timestep, aiming for an optimum of 10-15 iterations per time step.
