Base Contact Models

A Base Contact model defines the physical collision between particle materials or particles and geometries.

Typically, the base model consists of spring and damping forces in the normal and tangential directions. You can add only one base model per simulation. There are different physics models available for Multi-Sphere/Sphero-Cylinder, and Polyhedral simulations. 

For simulations using a custom API contact model, select the No Base Model in the Base Model list. You can add the following models as a Base Model to a simulation.

Multi-Sphere and Sphero-Cylinder

  • Hertz-Mindlin (no slip)
  • Hertz-Mindlin with JKR
  • Hertz-Mindlin with JKR V2
  • Hysteretic Spring
  • Linear Spring
  • Edinburgh Elasto-Plastic Adhesion Model (EEPA)

Polyhedral

  • Hertz-Mindlin Nassauer-Kuna (Polyhedral)
  • Hertz-Mindlin Effective (Polyhedral)
  • Volume Spring Model (Polyhedral)
