free CFD
 

Hi
We are using ansys CFX and not we are looking for free simulation software (too many money each years to pay!!!:mad:)

Which do you suggest us?
The most of our simulation are about fan!

thanks

Dear Sergio.

there is plenty of options on line but i would reccomand to take a look at two project who are more developed and with the bigger user base:

OpenFOAM (you can even find a dedicated section here on cfdonline)

and

code-saturne

best regards

Thanks

I'll check your proposal
:)

Hello Sergio,

I fully agree with you. On the other hand, familiarizing with a new software may require a significant effort. An alternative to that is a new collaborative approach, eCFD, that we have developed with the intention to make CFD accessible for the wider communities (see http://ecfd.nlr.nl/index.php/why-ecf...escriptions/84).

It will allow you to perform flow simulations at your discretion (on-demand) through an email interface, after a parametric scheme of the simulation has been developed collaboratively (e.g. together by you and me). The parametric scheme encompasses the flow, geometry/grid (e.g. twist, planform, 3D profile of the fan) and, if appropriate, solution procedure. This framework is suitable for exploring the design space by varying the parameters, e.g. to perform a design of experiment, define a surface-response, train an artificial neural network, or just a simple parametric study.

Please contact me at http://ecfd.nlr.nl/index.php/contact-us-now for further information.

Best regards,
Bambang

I propose OpenFOAM as well. It is free, there is a lot of solvers already included and the community is growing. Also, there are industrial applications.
On the downside it takes some time to get into it even though there are a lot of great tutorials (Chalmers PhD course above all).
