Reply To: Why do Fluent 2015 and Fluent 2020 give the big differences of results?

[SEANGHAI]

Thank you for your reply! And Yes! Both are converged! 2020 is converged at 124th iteration and 2015 converged at 420th iteration. Bothe are being run by the couple solver. But for 2020, it is automatically chooses Pseudo Transient Method, but 2015 does not, so I think this is why the results are different. n
