Greetings!

I am starting to set up some simple cases in OpenFoam, and I am trying to convert a mesh generated in Salomé to OpenFOAM format.

When running ideasUnvToFoam I get the following:

Code:
/*---------------------------------------------------------------------------*\

I have exahustively searched for possible explanations, and I see some people have had the same error but with no solution...

In the following link (http://www.openfoam.org/mantisbt/view.php?id=1142), it is explained as a system dependent issue... But I don't know what to do about it...

I am getting the same error with OpenFOAM 2.2.2 and 2.2.3. I am using Salome-Meca 2014.2 LGPL to generate the mesh...

Hoping for some guidance,

Ricardo

Hi Ricardo,

did you try that script https://github.com/nicolasedh/salomeToOpenFOAM
mentioned http://salome-platform.org/forum/for...3165#118130563 ?

Sorry that I do not help with your question hope that script might be another work around. Heard that ideasUnvToFoam is not the best choice anyway.

Hey!
The problem was exclusively in the mesh generation in Salome. I first tried to convert a mesh without any face groups, and ideasUnvToFoam worked fine. Subsequently I read here and there some reccomendations and I arrived to the following steps (I am working with a single shape at the moment):

Geometry module:
a. Build geometry
b. Create groups for the boundary conditions

Meshing module:
a. Create the mesh
b. Take over the groups for the boundary conditions (surfaces) from the geometry (it is case sensitive to select "create Groups from Geometry" instead of simply "create Groups")
c. Export mesh in UNV format

With the system folder containing the controldict file and the mesh (unv format) in the root folder, ideasUnvToFoam works just fine.

And to think I messed up my graphic card settings an entire weekend trying to "solve" the problem eslewhere...
