Anyone had any luck with Open Source CFD??

Anyone had any luck with Open Source CFD??

Post

I'm just trying to find a way of running a couple of models of my next Electric Race car in CFD.

I've downloaded both Open Flower and Open Foam, but i've had no luck at all really, I've tried running Open Foam in Linux but no luck.

So I was wondering is there anyone out there that would be willing to run them for me??

I know I ask a lot of you all on here but trust me, it is greatly appriciated.

are you still at a uni? if so you can probably get a copy for flow works for free its not great but its miles ahead of the open source stuff

you might still try to get an education license. they like to sponsor FSAE and solar car teams

That's totally false. The open source stuff is as good as codes like fluent, let alone flow works, which is honestly worse than no CFD at all. There are several F1 teams using it, and a few large aerospace companies as well. A number of UK motor sport consultancies, too.

OpenFOAM is an excellent tool but has a very steep learning curve. Indeed it offers the majority of the functionality of the commercial codes, with the added bonus that the algorithms are open for anyone to see and modify if so desired. It also now comes with an automated meshing tool (castellated mesh type, very similar to Harpoon) which should have you run flows around complex geometris with little effort if at somewhat reduced fidelity.

Contact me if you want guidance or other help.

i was thinking more ease of use not so much functionality

but yes flow works isnt that great of a code but its fine for rough body design that Green power will be using it for

I am just being anal here, but STEEP learning curve means the curve of learning over time is steep, i.e. high slope. That means you learn a lot in a short amount of time.

flynfrog, my opinion is that its better to do analytical work. The wrong answer is worse than no answer, as it sends you chasing after things that don't exist. The value of flowworks in design is useless, but it does have value in starting to learn about CFD.

I can agree with that after trying to learn Star Cd for a year it was nice to run a few sims in flow works then have a better idea of what I was doing going back to star. The biggest problem with most cd packages is they are about as user freindly as a child safety cap on a fire extinguisher
