I have created a 3d geometry with gambit and meshing with ansys meshing and i exported as .msh

when i type fluent3DMeshToFoam singleserpantinefine.msh

where is the problem ?


http://albertopassalacqua.com/?p=885 is it safe ?

Greetings Evangelos,

The fix that is presented in http://albertopassalacqua.com/?p=885 is meant to be used as follows:

1. Edit the file "~/.bashrc" and add to the end of the file a new line with:
   

   export AWP_WRITE_FLUENT_MESH_ASCII=1

2. Start a new terminal.
3. Launch Workbench directly from the new terminal.
   • If you are only able to launch the Workbench application from the menu, then you might need to logout and then log back in.
4. Export the mesh on Workbench again to ".msh".
5. Now you can go back to the terminal and convert the ".msh" file to OpenFOAM.

Best regards,
Bruno

Hi,

I would like to trythis fix to see if I can succesfully import my Ansys mesh. However I am running Ansys Workbench in Windows, how can I specify that I would like the .msh-file in ASCII-format?

Jone

Hi, Jone,

Depending on which ANSYS version you are using. If you are using V14, then, you do not have to set the ascii = 1 throught windows variable.

In Workbench Meshing, seclect "Tools", then, click "Export" under Meshing. Set ANSYS Fluent format to "Ascii".

After this, you can export the mesh and select Fluent *.msh format.

Thank you very much both of you! I will check this out as soon as I get my new installation running.

Have a nice day!

Hi,

I`m trying to export a mesh file from Ansys to OpenFOAM but received this error message: -

Can anyone help me on that? I am using Ansys version 16.2 and i have followed the treat to change the file format to ASCII yet the problem doesn`t resolved.

I have no idea on the following statement: "stripInvalid() called for invalid fileName surface3.STEP" . I placed this geometry file in the same folder with surface3.msh. If i removed this file from the folder, i get an error message :-

--> FOAM FATAL IO ERROR:

Thanks.
