Size of the worl CFD community

Anybody could give me an order of magnitude of the number of poeple using CFD in the world ? Is it several hundred thousand, about a million, or several million ? Thanks for the answer !

Re: Size of the worl CFD community

I can give you a bound:

between 1 and ~7billion people use CFD

Re: Size of the worl CFD community

roughly ~2billion are illiterate and there are some who are litterate but do not work (house wives and elderly etc). So the safer bound will be 1 and ~4 billion. We are narrowing down.

Re: Size of the world CFD community

Seriously, i dont think my question requires such "low key" comments.

Re: Size of the worl CFD community

So ~7billion - illiterate - literate(but dont want to iterate) = iterate?

Yeh, I could.

Re: Size of the world CFD community

Its very difficult to estimate , you can perhaps estimate the people currently studying in colleges and then say fraction of them study mech and fraction of them work in CFD. Even after that what about those who have completed their study and are working (for them you have to estimate how may companies are working in CFD field and their strength). But the main thing is who will do this much math, i am already math-illetrate.

Re: Size of the worl CFD community

I would guess that somewhere between 10^3 and 10^4 use commercial codes in industry.

That is probably a reasonable estimate of the actual CFD practitioners.

I would suggest that the number of researchers worldwide could probably add another 2-4000 to that list.

Re: Size of the worl CFD community

It is interesting.I would guess round 1 billion.

Re: Size of the worl CFD community

let's say 1000 licenses per big CFD software company each license has 5 user

1000*5=5000

there are about 5 generally used CFD codes 5000*5=25000

+ some other software codes and own codes users,(20%) 25000+ 25000*20%=30000

If we count the university student who got the CFD education, then (30%)

30000+ 30000*30%=39000=3.9e+4

I do not know it is converged or not, what's your opinion?

Re: Size of the world CFD community

Thanks, this confirm my inital guess I am gonna round up to an order of magnitude of several 100 thousand so i am gonna go with there. Thanks to the one who provide usefull information ... for the rest i am glad you had time to lose. Thanks again

In http://www.cfd-online.com/About : "Today CFD Online is the largest and most popular CFD site on the Internet. During a typical week CFD Online is visited by 10,500 people (unique IP addresses) ... (figures from 2004)."

Re: Size of the worl CFD community

What kind of idiot asks this question?

 Jonas Larsson November 29, 2005 15:54

Re: Size of the world CFD community

Yep, that is over one week. Over a year the number is > 100,000 unique IP addresses visiting CFD Online. I'd guess that the number of CFD students, engineers and scientists in the world is around 100,000 or even more.

 Rui November 29, 2005 20:14

Re: Size of the worl CFD community

Surelly the kind a lot less idiot than the kind of who asked your question.

 zxaar November 29, 2005 20:25

Re: Size of the world CFD community

there is a large percentage of people who do not visit cfd-online and work with cfd, for example i know around 10 people with my company that work with cfd and do not visit cfd online. (apart from me only one other guy occasionally visits cfd-online). So that makes the actual number much higher.

 thomas November 29, 2005 22:18

Re: Size of the worl CFD community

I appreciate your answer Rui, and thanks for the update on the number of log on CFD online, i think x00 000 is a good estimate, dont need more. I am just surprise that how such a simple and "idiot" question can raise so much useless comment. Usually people pass there way when the question is not interesting. Is poeple get lost when there is no math, meca or programming involved ? Thankfully there is some people who kep there head above sea level.

Discussion closed.
