Ver : solidworks 2017 SP.2 / Flow Simulation
OS : Windowks 10 x64
problem : Flow Simulation Solving....
Calculation → Calculation Control Options → Refinement → Level 1 Click (Refine Mesh) ok
Calculation → Calculation Control Options → Refinement → Level 2 Click (It's been delayed for a long time.) / About twenty minutes.!!!!!
※ Is it a Service Pack 2.0 program problem?

The same model.
2017 Sp.1 is calculated immediately after mesh capture.
2017 Sp.2 is It's been delayed for a long time. / More than 30 minutes.
Mesh cell : 50,000(Start) -> 300,000(level1) -> 1,900,000(level2) (Delay section)
Hi Sang-Hyun,
Have you brought this issue to the attention of your VAR?
Also, where are you storing/accessing the CAD files from as you run the Flow Project? Are they stored locally on your hard drive or somewhere else like on a network drive?

S/W Install Program is Local Disk(C:)
Flow Project is Backup (D:)
And there was no 2017 Service pack 1.0 problem.
Only in Service pack 2.0!
We would need to isolate your problem further in order to tell whether the issue is unique to your machine's environment or a problem endemic to the software due to the version change. Have you tried running this Flow Simulation on another machine? Are you able to upload the file set here so I can try it on my end and see if the problem exists here too?
Like Ryan said, make sure you are working locally for sim. Sim pushes huge amounts of data around and if you are going through a network, that will surely slow you down.
Also, remember this little rhyme: Flow is slow. I used to run lots of flow simulations and usually had to let them run over night. And hope the next day that when I got to work it ran without errors, or I had to do it again the next night! I don't miss it.
This may seems to be a bit off, but does not hurt to try: setup the FSim problem from the scratch in 2017 SP 2 and see if it still takes long time.
Hi Sang-Hyun,
Without much more information I could not say whether it is a problem in the program or just the mesh taking longer to generate. Performance will, of course, decrease as the mesh refinement level is increased. Depending on how complex your model is this could cause a ver slow mesh generation.
There are other concerns as well. Where are you storing/accessing your CAD files from as your run this Flow Project on them?
