this is a great news!!

for comming questions on free code, cfd solver source code and other of such kind:

(1) not only opencfd is open source, it is released under GNU licence (interesting reading - not like EULA of MS :O))

(2) the important bits for users of a code released under GNU are these: (a) the source code of the program must be public and free. (b) users can use the code as they want. (c) users can modify the source code, extend it, but any code comming from changing the original source code is inheriting the license, so the changed source code must be again availible to anyone. (d)user cannot take the part of the code released under GNU and put it into his own code which is released under commercial licence. ....more to be find in the GNU licence.

I'm really looking forward to see where this is going to lead.

I agree with Matej,.... this is really important for students looking for "research porpuses software"... what a nice surprise,... I just asked about a suitable software for my work and now a ligth is shining. Let's try it.

cheers.

1) FOAM does not run under windows

2) rename it to *.tar.gz

This is really interesting news. I've never used FOAM myself, but I have a bunch of former colleagues at Chalmers University who have used it extensively. Everyone who has come close to FOAM seems to like it

Has anyone ever used FOAM for turbomachinery applications? Is the solver robust and accurate enough to handle high-speed flows with strong shocks?

Does the FOAM framework, or an add-on to FOAM, include typical turbomachinery features like rotational periodicity, computing in rotating reference frames, mixing-planes models between rotating and stationary blade-rows etc?

I am trying it. Actually my problem is till now I have been F90 guy, have to learn C++ first. I have already developed my own Turbo Code in F90.

Regards

Hi Jonas,

Do you know if the code FOAM has been entensively validated or not ? Also, have your colleagues published any papers using FOAM somewhere ? It would be nice to see how the code works before spending a lot of time to learn how to use it.

I'm new to cfd and would like to know what FOAM is?? How useful it is?? (except for the fact that it is now open source) Also how good is it in handlying thermal heating, aerodynamics and aerodynamic loads??

Heya,

The numerics part of the code has been described and validated in my Thesis. You can find it and a number of other papers (all done using FOAM) on http://www.h.jasak.dial.pipex.com.

There is also an incomplete list of papers on:

http://www.nabla.co.uk/main/mainhe77...researchPapers

I have been trying to keep an up-to-date list for myself, but the number of people using FOAM makes this quite difficult. However, a list of authors/groups in the papers is a good starting point. What seems to be missing is some more recent work on multiphase and free surface flows, aeroacoustics, non-linear stress analysis and automatic mesh motion. I am a bit uncomfortable putting people's names here, so please send me an E-mail if you wish to know more.

Looking at the examples on the web site and doing a Google search and then trying out some tutorials would be a good start

Hi Hrvoje,

Thank you very much indeed for your info. I am really impressed by your work. I have sent an email to you regarding other issues. Please check.

Kindest regards

Hi Hrvoje,

I forgot to ask if you could sent me info or publication list regarding incompressible two phase flow simulation using FOAM. I am particularly interested in particle tracking in tubulent flow.

Thanks a lot in advance.

As Jonas, I'm interested in the ''turbomachinery'' capabilities of FOAM, especially regarding unsteady rotor/stator interaction. Nobody using FOAM in this field ?

Thanks for the info Hrvoje. Releasing FOAM as open source is really an exiting development for the CFD world.

I'm wondering what Nabla's (or OpenCFD Ltd.'s) intentions are about the future development of FOAM. Will you follow the path of other large GPL based projects and establish a world-wide virtual development team where everyone who puts in enough competence and effort is welcome and gets write persmissions in CVS repositories etc? Or will you keep the future development of OpenFOAM more strictly controlled in-house?

How has the development and release process of FOAM been handled previosly btw? I imagine that although FOAM has not been open-source you still got a lot of contributions from users in academia. Has FOAM got a world-accessible CVS repository, bug & task tracking databases, established release process etc?

THe thesis link on the website doesnt seem to work. I am interested in the numerics aspects of it.

Also, it seems like FOAM is very object oriented (Honestly, I have looked at the source in any detail, just judging from your papers and a prelim look at the code) Have you ever tested performance of the code? Is there an issue with that?
