**System**  
Ubuntu 18.04 LTS  
CalculiX Launcher [v2](http://www.calculixforwin.com/)  
Salome v9.3.0

* * *

**Background**  
I made a simple box geometry and meshed with Hexahedral (C3D8) elements using Salome.  
Then I exported the `.unv` mesh.

Using the CalculiX launcher I converted the mesh from `.unv` to `.inp`.  
And I opened the mesh using the pre-processor. (`cgx -c Mesh_Coarse.inp`)

I am trying to export `.dfl` and `.flm` file, but when I do the following:

```auto
plot fa all b

```

I see this:

**Question/Discussion**  
Is this normal?  
What might be causing this?

Here is the contents of the exported file:

```auto
** DFlux based on interface
1, S?, 0.000000e+00
2, S?, 0.000000e+00
3, S?, 0.000000e+00
4, S?, 0.000000e+00
5, S?, 0.000000e+00
6, S?, 0.000000e+00

8, S?, 0.000000e+00
9, S?, 0.000000e+00
10, S?, 0.000000e+00

```

```auto

5, F?, 300.000000, 4.000000e+03
6, F?, 300.000000, 4.000000e+03
7, F?, 300.000000, 4.000000e+03
8, F?, 300.000000, 4.000000e+03
9, F?, 300.000000, 4.000000e+03
10, F?, 300.000000, 4.000000e+03

```

Please, could you post contents of the INP file? Maybe it was converted with mistakes.

@imirzov I could not upload the `.inp` file directly.  
But here is the [drive link](https://drive.google.com/drive/folders/1l41vKUvpr9NCSFU9qXEJ7ZEhcIXHaOtS?usp=sharing) for the files. Please let me know if you can access the.

This has all the files. (`.hdf`, `.unv`, `.inp` and the exported `.dfl` and `.flm`.)

I tried to export the mesh once again, and I could see the face numbers.  
I don’t know what the issue was/is.

This happened totally randomly. I will let you know if I am able to run the example.

Thank you for your help. 🙂

I’ve checked Mesh\_Coarse with [unv2ccx](https://github.com/calculix/unv2ccx). Looks like you’ve converted UNV to INP correctly. So the reason might be another. Good luck!

Ok, thank you for checking the files.
