Reply To: Fluent not starting first iteration

Check the load on each core, you'll have 4 running flat out & the rest doing very little. With only 4 cores available due to the licence it's going to take a while to solve. There's a reason people use parallel/HPC packs. Note, if that's 18 real and 18 virtual cores do NOT try running on all 36, the solver won't share the resource well between the real & virtual core and may even slow down overall.
