CONVEX TRIANGULATED

Convex is a very flexible shape option for sharp edged particles. It is typically used if interlocking effects are important. It is the physically most advanced shape model available and can directly reproduce all effects of non-sphericity.

FIBER AND BONDED

Bonded particle models can be used to model arbitrarily shaped particles together with breakage. It can also be used to model the deformation and onset of breakage of large solid bodies. Aspherix® also features the world first fiber model which is especially suitable and efficient for light-weight fiber structures. It can be combined with liquid bridges as well as breaking, buckling and bending.

CONCAVE TRIANGULATED

This is the most versatile shape option for arbitrarily shaped sharp particles. It can be used to model hollow particles and it is very useful to get accurate descriptions of packing structure and density.

ALL SHAPES

MULTISPHERE

This is a versatile shape model that allows to depict arbitrary shapes by sticking spheres together. It is a useful simple model for introducing non-spherical particle behavior in many applications.

ALL SHAPES

SPHERE

Spheres are the simplest shape model and computationally most efficient. This shape model can be enhanced by rolling friction models to incorporate behavior of non-spherical particles despite the spherical shape.

BOX, CYLINDER AND ELLIPSOID

Analytical shape descriptions are often a very efficient way to model shape in DEM. Aspherix® can model many different shapes analytically, like cubes, plates, rods, cylinders, ellipsoids or tablet-shaped particles. These shapes can also be mixed seamlessly.
