Dear all,

I am new in OpenFOAM so i am sorry if i dont know too much about it. I had a file in .dat extension and i would like to mesh it. They file is a binary and i would like to produce a mesh from it. I have tried reading OpenFoam users guide book but it didnt help me a lot. (Any other suggestions will be more than welcomed). I know that i should change first of all the ControlDict and i supose that i should change the ascii to binary. But i dont know anything else

Please provide more infos. What program has been used to create the *.dat file?

Hi
I dont know how it has been produced since they gave it to me as just a file and its really big. (1.1GB)

Hi,

What program are you using to display the geometry? Got no magic crystal ball...

hi
As i stated above i am new to openfoam. I suppose that i have to produce the mesh and then i want to have a look in ParaView (4.1.0). Please find below a simple of my .dat file.

Greetings to all!

@charitonas: As cutter already indicated, the ".dat" file extension is a generic file extension. The file extension itself does give any indication of the software used to generate it.

That being said, on most Linux Distributions, it's possible to use the command file to attempt at figuring out the contents of the file. For example, if the file is named "thename.dat", then run:

file thename.dat

But honestly, I suggest that you have a good long talk to whomever gave you that file and ask them:

1. In what specific format is that file?
2. Can they export the geometry to another format? Preferably to STL format - http://en.wikipedia.org/wiki/STL_%28file_format%29 - so that it can be used with OpenFOAM's meshers.

Otherwise, the file you've got is as good as a file made up of a random set of 1 billion bytes .

Good luck! Best regards,
Bruno

dear wildcat,

thank you very much for your reply. Indeed, it help me a lot. I will try to ask them but from what i know it was the geometry of an object.
I haven't got any reply for them but just a note.
They gave a zip folder with two files in it. The first one was .raw and the other .dat
Is there any way to produce mesh from the .raw file or no?

Thank again for the help

Hurray for generic file extensions...

Try importing in Blender, using the "io_mesh_raw" plugin: http://wiki.blender.org/index.php/Ex...rt/Raw_Mesh_IO
Don't know how to use Blender? Check this website: http://wiki.blender.org/

Dear wyldcat,

thank you very much for all this help. I will try to find out the information and come back in the next 2-3 days.Thanks again

hello Charitonas

did you find the solution? I have the same problem. I want to simulate fluid flow in porous media. I have .dat file not .stl or .obj, I couldn't find any converter to .dat to .stl.

Thanks in Advance
