In Flow simulation,
When "Delta" has to be less than "criterion", The goal is 100% converged.
Delta is the different between Max. and Min. value over the convergence analysis interval range.
Generally, Goal plot delta & Goal value delta is equal value.
See the below image,
In spite of convergence(iteraiton=334), Goal plot Delta and Goal value Delta is so different.
Why?? I don't understand in this situation.
