Hi everyone!

I am a new of OpenFOAM and hence AeroFoam as well. In order to get familiar with it, I went to the following website and downloaded the Oblique Shock Test problem:

http://www.aero.polimi.it/freecase/?...:Oblique_shock

After uncompressing the folder, I tried to run it, but the following came on the terminal:

Hi,
I've tried to use AeroFoam 1.7.1 solver for the OpenFoam 1.7.1 tutorial case ObliqueShock, and I 've done all the correctoins which are given in the AEROFOAM QUICK START paper www.aero.polimi.it/freecase/?download=AeroFoam_QuickStart.pdf
but after entering AeroFoam I see the following message:

Please, Help!
Thank you very much in advance!

Hi All,

I had the same problem like you when I tried to use AeroFoam solver to test that case. Is there anybody treat this problem?

[aerothermal]

See that someone developed a 1.7.1 version.
I have not tested yet.

https://sourceforge.net/projects/aerofoam/

[aerothermal]

I had same problem here when running the Onera M6 wing test case downloaded from AeroFoam site and using AeroFoam for OF1.7.1.

And now I want to test this solver with a tutorial case : the oblique shock.
However, (after 'BlockMesh'), when I launch AeroFoam, I have :

Hi
Does anyone have a benchmark for AeroFoam Solver in OpenFOAM-1.7.x or 1.6-ext or newer versions?

[avani]

Hello all,

I am a student and I am pretty new to CFD and specially, OpenFoam. I am trying to install the AeroFoam solver in an OpenFoam 2.3.0 version. Does anyone know if this will work since the page I got the AeroFoam file from only lists 1.4.1 as the version to be used.

Also, if it works, how should I go about installing this feature?

Thank you for all your help!

[wyldckat]

Greetings Avani and welcome to the forum!

The source code made available here has two versions:

• AeroFoam-v1.tar.gz, which is made to work with OpenFOAM 1.4.1
• AeroFoam-v2.tar.gz, which is made to work with... OK, in the file "myOpenFOAM.H" says this:
  

  Cross-compatibility for OpenFOAM 1.5-dev, 1.6-ext, 1.7.1 and 2.0.0

With any luck, this works with OpenFOAM 2.3 and 2.4... But I would strongly suggest you first try using OpenFOAM 2.0.0 for testing if you can get any results with this in the first place.

As for installing it... see the description given inside the file "Make/files".

Best regards,
Bruno

PS: I've moved your post to the original thread dedicated to AeroFoam, for keeping everything on the same topic in the same thread.

Hi Giulio.
I have learnt about FSI using open-source software. I 'm very interested in your thesis. But my OpenFoam software 's version isn't 1.4.
Can you give me ubuntu deb pack openfoam 1.4 or AeroFoam for newest version of OpenFoam 3.0.1 to my email (tuananhtran.kthk56@gmail.com).
Thank you so much.
