Selecting the Physics Models for Meshfree DEM

When you select the Meshfree DEM model, all other models that are typically required for this type of simulation are selected automatically. You also account for the effect of gravity on the particles.

To select the physics models:

  1. Right-click the Continua node and create a physics continuum.
  2. For the physics continuum, select the following models, in order:
    Group Box Model
    Optional Models Meshfree DEM
    Lagrangian Multiphase (selected automatically)
    Multiphase Interaction (selected automatically)
    Discrete Element Model (DEM) (selected automatically)
    Solution Interpolation (selected automatically)
    Time Implicit Unsteady (selected automatically)
    Optional Models Gravity
  3. Keep the model selection window open while continuing to the next step.
