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

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).
