Hi naveen,
I try this, but I have the same mistake, I can't send you the mesh, because my tutor don't like send it.
fluent3DMeshToFoam has this mistake:
From function fluentMeshToFoam::lexer
in file fluent3DMeshToFoam.L at line 747.

But fluentMeshToFoam has the next mistake:

hi bego,

In the text format what you have got in Tgrid, at the first line change Tgrid into fluent and follow the instructions what i mentioned previously.

Hi naveen,
thanks, I go to try it

[bego]

hello,
I have other problem with fluent file case. When I put in the terminal fluent3DMeshToFoam FILE.cas I have the next mistake:

Create time

Do not understand characters:

in file fluent3DMeshToFoam.L at line 747.

FOAM exiting

With fluentMeshToFoam I have a more big mistake, Can someone help me?

Thanks

[naveen]

hi bego,

Can you send me your mesh file. I can convert that into foam format.

[bego]

Thanks naveen, but my teacher project don't want that other people has the mesh. She knows another teacher who knows OpenFOAM in Zaragoza, first we try to get out there.

Thank you very much for everything

Hi Neveen,

I have a problem in converting the fluent3dmesh to OF1.6. I Copied the Msh file into my case directory and type fluentMeshToFoam extension.msh, but i got this error. can you help me?

hello!

one stupid question (newbie):

i've just converted my .msh file into an ASCII format file for OpenFoam with the command "fluent3DMeshToFoam". everything fine. but now i would like to view this converted mesh via paraFoam and i don't know what to do. i have no blockMeshDict file so i cannot use blockMesh....

could someone please help me?

thanks

[naveen]

hi grandgo

Just go to the file where your case is located, and type paraFoam and switch off all the vol Field status and accept it.....


regards,

NAVEEN

[grandgo]

thanks naveen!

Once you have the file open in paraFoam, you can check the box "Include Sets" on the panel and it will allow you to view the sets that the checkMesh utility may write if you have skewed faces or nonOrthofaces.

Hi farghaim,

I am new in OpenFOAM and I´m trying to convert a .msh from FLUENT to OpenFOAM. I´m using OF 1.7.1. I got the same error message you posted in May 2010. Did you find any solution to this problem?

I paste you my message in OF

Did you also tried fluent3DMeshtoFoam ?

[martals]

Thank you Matthias for answering my message.

My mesh is a 2D bifurcation, that is why I am using fluentMeshToFoam. Does fluent3DMeshToFoam work better than fluentMeshToFoam? Do you know what can be the source of my errors? I don´t understand what they mean or how to solve them!

Thanks,

Marta.

[Roark]

I had the same error message as OP. The problem was that the mesh exported by Fluent was in binary format, not ASCII as is required by fluentMeshToFoam. To export as ASCII in ANSYS Meshing, do Tools > Options > Meshing > Export and you will see the option.

I had the same problem. Saving in ASCII-format fixed it!

Hi everybody,


I still have the same Problem in OpenFOAM4.0 - referring to below .

can u help me converting my mesh?

Hi
I got similar problem.
I opened msh file in ICEM, saved as fluent mesh there and now it works.
