EDEM Creator
EDEM Creator is the pre-processor for creating an EDEM simulation model, including setting up equipment and defining the generation of bulk materials.
- Creator Tree-Project
  Creator Tree-Project allows you to define the title and description for the simulation.
- Creator Tree-Bulk Material
  Creator Tree-Bulk Material allows you to add bulk material and bulk material particle shapes to a model and define their interactions.
  - Add Bulk Material to a Model
    A Bulk Material comprises the particle bulk material properties, particle shape, and size distribution.
  - Add Bulk Material Particles
    You can add bulk material particle shapes such as Multi-Sphere, Polyhedral, and Sphero-Cylinder.
    - Add Multi-Sphere Particles
      You can define a particle using one or more spheres, and overlap multiple spheres to create Multi-Sphere particles.
      - Generate Multi-Sphere Particles from a CAD Template
        You can use imported CAD meshes created in other applications as particle templates that provide instructions on how to create a particle whose properties are automatically calculated.
      - Add a Particle Shape from Library
        You can add and describe various particle shapes from the Library.
      - Modify a Particle Shape
        You can modify a particle shape by changing the values in the table.

      - Calculate Particle Properties
        EDEM allows you to configure the particle mass, volume, and inertia either manually or automatically.
    - Add Polyhedral Particles
      You can define a Polyhedral particle using one of the basic polyhedral particle shapes or an imported CAD geometry.
    - Add Sphero-Cylinder Particles
      You can define a Sphero-Cylinder particle using the length and radius, where the length is the total length of the particle including the rounded ends.
  - Create and Define Meta-Particles
    A Meta-Particle is a collection of individual Multi-Sphere or Sphero-Cylinder particles bonded together using EDEM’s Bonding V2 contact model.
  - Size Distribution for Particle Shapes
    You can specify the size distribution for the particle shapes in each Bulk Material including Meta-Particles.
  - Material Starter Packs
    The Soils Starter and Powders Starter packs are installed with EDEM.

Export a Particle Shape

You can export a particle shape for use in other EDEM simulations after it has been defined.

To export a particle shape:

Right-click the particle and click theicon.
Save the file to your Particles folder by navigating to Tools > Options > File Locations.
Files are exported in the .dem format.
