hi Pei-Ying Hsieh ,

I am able to convert the 2D mesh created in workbench 14 to openfoam readable format fluentMeshToFoam flat.msh .
It automatically takes it in 3D which i found using Paraview .

Now here comes the problem .

I tried running blockMesh after that . IT shows some errors .

I checked the Run/try/constant/polymesh folder for blockmeshdict file .
it has all files like
1.boundary
2.owner
3.faces
4.cellzones
5.facezones
6.pointzones
7.points

but it did not have blockmeshDict .

Because of this it showed the error when i tried running blockMesh inside the respective folder.

So how can i proceed further to get the results . ??

Thanks
sud

Hi,

After you converted the mesh to openFoam, you do not need to do blockMesh. Just open the boundary file to edit your boundary conditions.

Good luck!

PSYMN,

How do I export mesh from ICEM CFD to ASCII format ? I'm using linux OS.
Alternatively, is there any way to convert .msh format to ASCII format ? Please help. Thanks.

ICEM CFD native mesh files (*.uns) are only available in binary.

However, FLUENT mesh files (*.msh) are available in binary or ascii. ICEM CFD can read and write both...

So, there may be a better way to convert a binary *.msh file to an ASCII *.msh file, but one way to do it would be to read the binary file into ICEM CFD (File => Import Mesh), and the output (use output tab) it to Fluent as an ASCII file.

As you said , i tried finding this in the meshing module , there is no export option found in the meshing .

Take a look at this .

You can set an environment variable to get the mesh in ASCII:

AWP_WRITE_FLUENT_MESH_ASCII=1

Hi,
I also want to export my mesh file as ASCII.
Unfortunately it doesn't work, neither with using the environmental variable nor with changing export to ASCII. The file is still saved as .msh.
Can anybody please help?

The ASCII file still uses the .msh extension...

Did you try to open the file with a mesh editor? Let confirm that before we try anything else.

I tried to convert it using fluentMeshToFoam, but it didn't work.
Although it looks like the mesh is converted there is no output, just some empty text-files. And at the beginning of the converting there are always messages like "Embedded blocks in comment or unknown"...

Hi Simon

I'm not sure what the environment variable means

In gambit you need to export your mesh (in 3D) as a fluent 5 file. This is a .msh file.
File > Export > 3D Does that make sense?

Hi everybody,

are we able to get a mesh file from Autoform software and read that
into ANSYS-FLUENT?

I would like to simulate at different times what is the pressure and velocity
for different meshes of the autorm mesh.

I got exactly the same problem, I got an academic 14.0 version and there is no such an export option in the meshing, and setting the environment variable doesnīt work either. Its the same binary format that fluentMeshToFoam canīt convert. Any clues?

Hi man,

I am also stucked with the same problem.

I changed the Environment Variable to 1 ! but its not working.

can you let me know how u did it ?

What I am trying to do is,

I made a Geometry in Catia > Exported as .igs file
Then imported that .igs file to Ansys Workbench.
Did the Meshing with Ansys Workbench Mesh.
then Exported it as .msh file.

then in linux terminal with Fluent3DMeshToFoam xyz.msh

but it is giving outout as,

Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Dimension of grid: 3
Number of points: 9362
Number of faces: 88497
Number of cells: 42058
--> FOAM Warning : Found unknown block of type: "3010"
    on line 14


--> FOAM FATAL ERROR:
Do not understand characters: B▒E
    on line 15

    From function fluentMeshToFoam::lexer
    in file fluent3DMeshToFoam.L at line 748.

FOAM exiting
I doubt whether the conversion from Binary to ASCII has taken place or not ?

Can you please throw some light on it ?

Will this code works in WB 14.0 and higher versions.??. I have set the environment variables and unable to read the mesh file in ASCII format. I opened mesh file in word pad, notepad and word but getting strange outputs..
Where I can read the mesh file correctly.??.

Any help would be appreciated..

Thanks in advance..

Even I wanted to convert binary mesh file to ascii format so to import in open foam.
Since i followed the instructions and made the environment variable but its not happening, I am using workbench 14.0

Please guide me with this issue...

I believe after R14.0 there is no need to change the environmental variable. However, there is a setting within the preferences/settings inside Workbench. I am not near my work pc to document the steps, but there should be a setting for mesh export in one of the system preferences menus.
