Hi guys!

I am fairly new to to ANSYS CFX. I am simulating a Multiphase, Crossflow turbine (Air and Water). I have two domains, the whole casing, and the rotating rotor.

I was running my solver and initially had 4 variables to monitor (RMS of Mass and Momentum). At around 480 steps, additional 4 variables appeared and the original 4 stopped solving, as seen in the continuity of the graph. (see thumbnail).
I simulated this one twice, the first one was up to 400 steps, i paused since my laptop was heating, i then continued until i got that separation in the graph. My limit was 1000 iterations on both.



What is the meaning of this? thank you very much! My knowledge in Ansys is not that in-depth yet.

I have uploaded a picture of my solver for reference

Opaque will become famous soon enough
Your solution seems to have run for 480, stopped, modified something in the multiphase setup (like activating homogeneous model) and restarted.
