Convergence Control

CFDJan · September 21, 2022, 10:45

I am running steady state simulations for a radial compressor. As a convergence criteria I want to set the change in massflow at the outlet.
So if the change between two iterations is smaller than 0,0004% then the simulation should stop.
How do I implement this stopping criteria?

Hello!
Have you tried with the manual of the software?
You need to right-click on "Stopping Criteria", then "New Monitor Criteria" and you select your monitor and the value that you want.
Let me know if you succeed or not!

StarCCM wont let me select "New Monitor Criteria"

that´s weird, when Star doesn´t let you select it?
Before initializing the solution? Does any message appear?

Perhaps basic question but have you created a report and monitor for whatever it is you want to monitor?
