Dear Community,

for convergence criteria I am looking at the Imbalances. The weird thing is, that in my .out-file the 'Domain Imbalance, in %' line is missing.

I will attach part of the .out-file and I would very appreciate if someone could help me with this.

Also for convergence criteria the imbalances should be smaller than 1% right? What do you think about my imbalances?

Thank you!

you could just have a look at the imbalances in the solver manager's monitor.

Thank you for your answer. So the imbalances in the solver manager are shown in %, arent they?
So when I have a value of 0.4 it means 0.4% and not 40%?
