Hi Simon95,

My project's end time was (and still is) set to 1s.

While I am still a beginner in ANSYS, I wonder what would happen if the total time was shortened to values like 0.01s or 0.1s while keeping the step size to 0.005s or 0.01s? If the software still gets stuck at "System coupling run completed successfully", could it mean that the step size or the total time is not the cause of this "stuck issue"? Just a food for thought...please don't feel the need to answer this question
