Hi, I am new in Comsol. I encountered a problem ,the computing remain 93% for a long time, and the convergence curve always fluctuated. The figure is attached. Anyone konw how to solve this problem, and accelerate the convergence.

Hi,

Convergence depends on many things so it would be hard to help you without more information about your model and how you encountered the problem.

In general for convergence issues you want to play a little bit with the solver's parameters, so I encourage you to read the doc on it and make your tests!
