Different versions different results

      I am using ANSYS 2020R2 and Ansys 18.2 to solve the same problem the mesh used is the same and all the solution's parameters are too yet I still face a difference of 7% in my results .

      Most importantly, the solution using fluent 18.2 takes up to 9 hours the solution using 2020R2 takes under an hour to solve

      Any idea what is the reason behind this difference

      What models are you using, and how does the convergence compare?

      viscous laminer and they both converage at 1e-6

      residuals as well as the monitors are the same in both cases

      And what monitor/result is different? Please post images to show the changes otherwise there's not a lot we can do.
