Flow-Simulation with roof of a house

PHX · May 14, 2009, 03:12

Hello everybody!

I'm very new to the topic of CFD. I'm engineer of electrical engineering/automation engineering, but now I've got a new research project hosted by my university.

The basic intention is to simulate the wind flux on houses especially on the roof. With a result to show possible turbulences and so on.

I just searched the internet for simulation tools and found different things like FLUENT, ANSYS CFD/CFX and so on. But I know that companies want to sell their software so they won't tell me what is the best to accomplish my new project.

So I registered here to ask if somebody already got experiences with this topic and maybe is able to give me some hints to choose the right software, etc.

Big thanks in advance!!

Best regards, Markus

So nobody got an idea concerning this topic or is this too easy to write an answer?

It all comes down to price and the value you get for it.
Fluent is number 1 for industry use in my eyes, yet you pay the price for it.
I would say google around on cfd architecture topics and you should get an idea on hwat you require.

your question is a little bit to simple. More specifications are needed to give a good answer

Also: please consider your cfd level before attempting any simulations, you wouldnt be the first to interpret the wrong results as correct. The theory behind this subject is more important then just filling in some numbers

I agree with what Bram said. You must talk to your friends there who are working in CFD.

As Bram told you that Fluent is number 1 commercial CFD solver, it is costly too, but if you search the academic license will be of lower cost.

OpenFoam is well known free CFD solver available on net. But again you need to take help of some CFD expert there.

With best regards

Thanks for your advises! I found a professor teaching CFD at my university, will meet him on friday, so I will learn more about to handle my problem in a direct way.

Thanks again.

Regards, Markus

Hello Markus,

Well I am looking for some simple pictures too to explain to someone who does not have a background in CFD. The problem is the same - forces on the windward and leeward side of a roof/building. Can you let me know if you find something. A web-page showing a schematic would be good too.

Thanks
