Hey All,
I'm currently working on a comparison between openFOAM and cfx, and therefore I need meshes in both formats. I started with the forward- and backward-facing steps of the tutorials and converted it with foamMeshToFluent without any error message. After that I tried to load the mesh into icemCFD to convert it to the cfx format. But an error occured which is obviously due to the last part of the converted fluent-mesh. Here a lot of 4s appear, which seems quite strange and looks like that:

...
4 299b 299c 2938 2937 13ba 0
4 29ff 2a00 299c 299b 141e 0
4 2a63 2a64 2a00 29ff 1482 0
))
(12 (1 1 1482 1 0)(

...
4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4)())
(39 (1 fluid fluid-1)())
(39 (2 interior interior-1)())
(39 (10 pressure-outlet inlet)())
(39 (11 pressure-outlet outlet)())
(39 (12 symmetry bottom)())
(39 (13 symmetry top)())
(39 (14 pressure-outlet obstacle)())
(39 (15 pressure-outlet defaultFaces)())

I also tried to convert the openFOAM mesh after solving the problem, as this converter is presented as a post-processing tool but I got the same results. Does anyone know if this is a bug, or if this must be due to an input problem???
Or has anyone already a converted mesh of the tutorial examples (forward- or backward-facing step).

Cheers
Florian

Hi Florian,

I could convert with the command foamMeshToFluent <root> <case> the Foam mesh to fluent mesh and then import it into the preprocessor of cfx. I use cfx v11. What i was not able until the moment is to import it directly to cfxpost and to import also the results to cfxpost.

Best Gabriel

Hi,

do you know what is the meaning of the following lines:

Code:
(12 (1 1 1482 1 0)( 
4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 
... 
4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4)())
In my case, I use pure tetrahedron cells, so the edge number of each is 3. but in the mesh file converted from foamMeshToFluent, I got the following:

Code:
(12 (1 1 1482 1 0)( 
3  3 3 3 3 3 3 3
... 
3  3 3 3 3 3 3 3)())
best, OFFO
