Re: Why "Time dependent" slows simulation?
hi jerry, if you want to understand the nitty gritty of the calculations, check the technical reference and solidworks simulation kb.
but from a more practical perspective, this is a fundamental selection for your analysis similar to internal vs external. do you want a steady state solution or do you want a time dependent solution? ie, the results after a long period of time when the system settles or over time. there are very few problems where you need a time dependent solution for something that will be come steady state (take a look at the cylinder flow tutorial).
why does it take longer? because it isn't iterating to a solution, it is calculating every individual time step. you're working in real time, not just iterations. for some phenomena, the time step needs to be very small, which can lead to a long solve time. have al ot of cells? even longer. setup and run a steady state solution to get an idea of how the system will work before going to tiem dependent.

Re: Why "Time dependent" slows simulation?
Jared,
Just looked up some textbook, I think I got the points the code looks for steady-state solution (ignoring all previous history leading to that state) or it just do a laborous integration over time. No wonder the big difference in time.
Thanks for the answer!

Re: Why "Time dependent" slows simulation?
Jared,
Is is possible to probe individual points anywhere on the model, or on a cut plot plane, to see is pressure/temperature value? I know it is possible to use coutour/isoline to visualize that, but it would be great if individual points can also be picked.

Re: Why "Time dependent" slows simulation?
in your toolbars
in the results section of the flow simulation pull down menu
you should also find other methods if you look up probe in the help and tutorial
