The Automatic Sphere-clump Generator (ASG) is a software tool that generates an approximate shape model of a particle using spherical elements that is suitable for DEM (Discrete Element Method) simulation. Sphere-clumps can be exported for use with EDEM (DEM Solutions) or PFC (Itasca Consulting).
ASG is currently available as either a Matlab toolbox or a stand-alone application (requires Java). Both Windows and Linux systems are supported. Customised implementations are available upon

ASG Matlab version 200902M released
Matlab toolbox for fitting sphere-clumps to STL meshes of particles. Includes function for fitting, visulising and exporting sphere-clumps and particles.
ASG comprises a two-step process: Sphere detection, and sphere-clump optimisation. The following movies demonstrate the ASG method (NB: Adobe Flash player is required) .
