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

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.

couple more

I Envy ALL People who can use CAD LOL

same

i tried to learn but it was to hard

might have to take a tafe course

[crack]

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.

[ISL33P]

yeah I started using the first one....just have to do it a few times to get the hang of it

[crack]

if you need any pointers i'm happy to help. as said above, just draw random things and have a play. the tutorials are a good base to start from.

my 4 year old boy did this

[ISL33P]

thanks for that.

My 3.5 year old better get a move on then....LOL

[GT-RZ]

I have been using it as a digital and versitale drawing cabinet lol.

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

rb25gbox in to silvia...

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

This is some stuff I drew up

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

[JAS-25T]

Ariel,

I live locally and could easily knock up some of these items if you needed.

[ISL33P]

HI Jason,

Give me a call this evening after around 7 when I get home. I am dead set keen on getting these done.

Thanks,

Ariel

[JAS-25T]

Sorry mate, I didn't even see this until just now.

Surely it's too late.

I'll try call tomorrow some time.

[ISL33P]

where's my call?

[JAS-25T]

Sorry mate, I've been busy with some personal stuff.

Will endevour to give you a call before COB tomorrow.

[ISL33P]

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
