  Hello! I'm trying to run this calculation with gravity using Direct Integration. As it is shown, it does not converge in a practical amount of time (30,000-40,000 iterations). Will ISAT probably solve my problem without changing my final results (velocity and temperature plots, contours, etc)? Any help would be really useful!!

  What is the contour of? Where are the inlet(s)? Is it transient?

  Hello! It is the static temperature contour, steady problem. I switched to ISAT method and after 1 day or so it converged (the contour was smooth without the fluctuations) so its all right! Thank you for your help whatsoever!
