How to time simulations
Hey all grizzled Fluent experts,

Not a really difficult question I imagine, but I pose it anyway:

How do I time simulations (both steady and unsteady) in Fluent? Preferably some output connected to the hardware clock, but any relative time measurement would do.

Best Regards

Hey Sara,

Not being this sort of expert as well, you need to activate the unsteady option in the "Define > solver" menu. Then, you could choose whether you adopt 1st or 2nd order formulations (for time descritization).

Cheers, Amr

Re: How to time simulations

If you want to time iterations (in terms of CPU time) see - Though you need to input the number of iterations you wish to be timed.

Also, in parallel, you can use the Parallel>timer function. You can always run a serial job in parallel on just one processor, it does pose an additional load adding to the time slightly, but if it's relative measurements between your cases it'll be ok.
