Yade

reconstructed 3D volume to DEM

Asked by Othman Sh on 2019-04-08

Hi All,

My question might be off but its related to Yade.

I'm trying to model a porous media that is very heterogeneous random pore shapes. I have a real sample that I scanned in X-ray computed tomography and obtained a stack of 2D images then using image processing, I reconstructed a 3D volume of the sample as seen in this image (https://drive.google.com/open?id=12f0BrIsHsDJhfR6nzwUcNXa9VxTeZQZV).

Do you think its possible to convert this 3D model to an STL or GTS file and import it to Yade then fill the solid part of the volume by spheres? The reason I want to do this is to get a volume that has the exact same pore structure as the real sample while the solid is filled with spheres and I can run DEM analysis in Yade. I'm not sure if this idea is realistic, so please give me some recommendations or if you have other suggestions please let me know.

Thanks,

Othman

Once you obtain the STL or GTS file, yes it is quite easy to import into Yade and fill with spheres [1]. However, conversion of your "3D model" to an STL or GTS file is an entirely different question that is probably not answerable here.
