strange problem with fluent version 19.2

Hi all, 

I am running through a very weird problem. I have a simulation case, I ran it on a PC with Fluent 19.2 and the solution diverged in the first 40 iterations. Then I ran it (the exact same case) on a different PC with an older Fluent version, surprisingly, the solution continued until converged!!!!

I checked the values during the hybrid initialization for the same case on the two versions, I found that they are different even though the boundary conditions are exactly the same (it is the same case)!!

This is really confusing! Hope anybody can help me out.

Thank you,

Ramy
