Importing particles to other softwares

Submitted by mehbah on Wed, 04/07/2021 - 20:14

Hello everybody,
I need to import the particles created by LIGGGHTS to CAD software. I have defined a simulation box with all faces as walls and put some particles on it. When I dump the last frame outputs as a .stl file, nothing save in the file and CAD software show nothing. Should I mesh the particles? if yes, how?
I appreciate it if you help me.
Kind regards,
Mehran
