I was wondering if somebody could offer me some help with Fluent.
Ive done a 3d sim, I simply want to display the pathlines as shown here:
I know that I have to define where to release from but thats where I get stuck.
Say for example my flow domain is:
x = 10
y = 2
And then say my object of interest is at:
x = 4 to 6
y = 0.75 to 1.25
z = 1 to 3
How would I go about setting my pathlines using such dimensions as an example. Is this clear?

The thing about the F1 teams is that they are probably using 1000 core machines to do their CFD on as their models can go as high as 100 million cells

... that is IF you don't mind running the whole OS off of a virtual RAM disk and making your entire computer run like a slug in a coma. Booting from a live CD is great for a quick demonstration, but terrible under a heavy-use scenario.Just_a_fan wrote:http://www.caelinux.com/CMS/ was mentioned earlier in the thread. Try that. You can download the iso, whack it on a disc and boot to it from the dvd. No need to take XP off your machine or dual boot linux from the HD.
If you are doing DNS at high Re computational power is never enough because you are not modelling turbulence, but directly calculating it (Direct Numerical Simulation). So you need much finer spatial grids and shorter time intervals.raymondu999 wrote:Forgive my ignorance, but I used to do something similar-ish for submarine propulsion; wouldn't these calculations, though you have millions/billions of them, wouldn't each individual calculation be actually rather simple? I don't remember the kind of computational power I was using, but I think for a golf ball (never did something that small before, so I could be wrong) that 670 procs would be overkill, no?
