Simulation taking more time

I am simulating Stirred Tank Reactor Simulation with Multiphase Flow which is taking more time is it normal or not? if not how can i reduce the time? is there i can do in Result Control or Numerics?

Link - SimScale

HI omzavare,

in general, the issue is that multiphase is always a transient simulation. Please have a look at these pages which explain the issues a bit and how to solve them.

Best regards
