Hey,

Ive just started doing 3d cad work and basic CFD. I have the software etc to do more complex CFD but I have just been modelling air flow through cooler piping n such. Want to eventually model plenums and exhaust manifolds. Im not interested in this as a profession or anything, Just a bit of a way to put off uni work.

You will find that you cant do CFD modelling without a thorough understanding of fluid mechanics. In making the model you have to have more then a basic understanding of what is going on if you are hoping to get accurate CFD results. The old story of shit in shit out...the packages are not smart enough to allow non scientists/engineers really exploit hwat can be done.

I did CFD at Uni in my final year of study, and hated it, because whilst i love the modelling i hate fluid mechanics :cool:

I found FEA is a little easier to use, partly because my mechanics is better then my fluids but also the software packages are a little smarter as stresses are far simpler then the head fark that is fluids >_<

If your studies are related to CFD then you should consider doing it professionally, especially if you enjoy it. Its quite a specialty skill that woudl be great to cruise the market place with

Yeh I didn't mind the fluid mechanics I did. Was a slight pain in the ass but it wasnt too complex. You are 100% right about needing to know more about fluids then just chucking in some air in and pushing run. What exactly did you study?

I dont think we have a CFD option in my degree at all, hence why I am just tinkering on the side. I deal a ridiculous amount with fluids in chemical engineering with liquid vapour equilibrium, polarity, viscosity, specific volumes and how pressure, temperature, volume, work, and heat transfer affect a system dynamically. But we havent gone too in depth into the fluid mechanics though sadly, that is more of the mechanical engineering side of things.

As for a specialty skill that does sound like a good idea, although I am not 100% sure how much that would be used around here in the mining industry. If I managed to get work with a petrochemical company then Im sure they would love me for it. I guess CFD would definitely be a little notch on my resume. :)

I just finished downloading solidworks and dam that thing is....ummm detailed!!!!! I'm with STR8E....tafe course sounds like a good thing

There are tutorials included. TAFE is overkill unless you are going to be using it professionally and need to know different standards. Do the tutorials and just mess around drawing random things and you'll learn enough to make up some fairly detailed parts.

Hicas eliminator (r33,r34,s15 etc) allows normal rear toe arms to be installed and acts as a brace too.

very handy indeed saves allot of time in the design process allows everything to be stress tested pre fabrication.

to the OP

find download the game STREET LEGAL (the first one) then download all the patches n mods n what not..

then import all your creations for teh awesomeness

its pretty much a game that you can get in to and change shit, you can import things created in cad and what not. im talking everything, wheels, exhausts,engine bits! its epic

just to give this thread a bit of a move on....here is of my first ones.

RB26 exhaust manifold flange with loft from port outline to ID of steam pipe to save a massive amout of die grinding and assist with port alignment and without lofting to keep costs down on cutting, 2axis vs 5 axid for lofted version

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
