Hello everyone!
I am trying to simulate the flow of water in a pipe full of marbles (glass beads). I am creating the geometry using Freecad. Inside the freecad, I use spheres as morbles and created the pipe from cutting one cylinder into another cylinder. In order to make it readable for OpenFoam, I exported it as STL file and then import it in Meshlab, and then export it back from meshlab. When I export it back from meshlab, the size of the file is so large (3.2 GBs) that my computer cannot open it. Does anyone know if I can do this in any other way.

BTW, I am doing a 2D simulation, but I am creating a 3D geometry.



Thank you all in advance!
