fluent3DMeshToFoam

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

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.

converting .msh fluentmeshtofoam

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 ?

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.

Remember to save mesh as ASCII!

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.

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

Hi everyone,

In my case the message "Embedded blocks in comment or unkown" is returned so many times:

Does someone know why this message is returned? It has to mean something so that if I know what does message mean, I can fix it in case it is a mesh problem....

Thanks,

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