Exporting GEOM from blender

[Hosein Sadeghi]

Hi, 

I cannot see the FDS input lines in the exported file when I make a complex geometry with GEOM. Could you please help me with it?

BR,

Hosein

Actually the geometry is saved to a .bingeom file. This is a binary file. How can I see the actual GEOM lines?

[Emanuele Gissi]

Hi Hosein,

when you export your case in the case directory, you find there:

• the .fds file, a text file that contains the GEOM namelist,
• and the .bingeom file, a binary file that has the description of the triangulated geometry.

I attach an example blend file. Remove the ".txt" from the name to load it in Blender. 

Is this what you mean?

Emanuele

Dear  Emanuele,

Thank you for your reply. Actually my problem is with the .bingeom file. The content is in binary format and it is not possible to manipulate it. I remember last time (last year) I used blenderfds, the GEOM was saved in .geom format. The .geom format is editable and I can see the VERTS and FACES. I need to get a similar file from blender fds. How can I do that?

 Please see attached file (please remove the .txt).

BR,

Hosein

In fact I removed the functionality of exporting VERTS and FACES, because I did not see any application of it.

They are imported but only the bingeom is currently exported.

Why don't you modify your geometry (vertices and faces) in BlenderFDS?

Hi, 

Thanks. Because I will then need the VERTS and FACES in another process. Could you please let me know which version has that capability? I can see there are four versions on github.

BR,

The last but one release still has it.

Let me know if it is worth reintroducing it and what use case do you foresee.

I am modeling pyrolysis of a cylindrical cable. The cable has multiple layers and each has a pyrolysis model. I needed to make different co-axial cylinders in Blender and then import them into my FDS input file. I don't know if I can do it with .bingeom file. 

BR,

Okay, you gave me a good reason to put it back in the next release. I'm opening an issue.

Thank you so much.

Dear Emanuele,
Is the .geom file generated in the latest version?

[Emanuele Gissi]

No, not yet. Probably in the next one. That version was already out when you asked.

Ok, which version has this feature now?

[Emanuele Gissi]

This morning I added the ability to export the GEOM ASCII format in the BlenderFDS development version.

To activate this feature:

* install the BlenderFDS development version

* edit the config.py file and set this setting to True:

```

## export GEOM VERTS FACES as comment
EXPORT_ASCII_GEOM = False

```

* close Blender and open it again

From now on all your GEOMs are exported in ASCII format: GEOM VERTS FACES...
