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-Geometries
Creator Tree-Geometries allows you to use Geometry sections to construct the environment in which your bulk material interacts.
Geometry Motions
Sections of a Geometry can be static or dynamic. Static sections remain in a fixed position during the course of a simulation whereas dynamic sections move. Sections can move under fixed translation, rotation, conveyor motion, or sinusoidal motion.
Motion Controllers
Unlike kinematics, you can add motion controllers to the geometry elements to allow objects to react to Particle-Geometry forces.
Specify a Force Controller
You can add a Force Controller to a Geometry. This creates a force on the Geometry which will react to the forces acting on the Geometries from the contacts with particles. Force Controllers can be used to allow the Geometry to move based on gravity.

Get Started with EDEM
The EDEM user interface comprises three icons for each simulation component - Creator, Simulator, and Analyst.
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.
- Creator Tree-Equipment Material
  Creator Tree-Equipment Material allows you to add equipment material to a model and define interactions between materials.
- Creator Tree-Geometries
  Creator Tree-Geometries allows you to use Geometry sections to construct the environment in which your bulk material interacts.
  - Select Geometry Sections
    You can select Geometry sections by clicking the required Geometry in the Viewer window. The Geometry in the Creator Tree is highlighted.
  - Create a New Geometry Section
    You can create sections in EDEM or import them from a CAD program to create particle factories.
  - Import Geometry Sections
    Instead of defining Geometry using EDEM, you can import Geometries from a variety of CAD applications.
  - Work with Geometry Sections
    You can replace, copy, and merge Geometry sections. You can also create Geometry groups.
  - Geometry Motions
    Sections of a Geometry can be static or dynamic. Static sections remain in a fixed position during the course of a simulation whereas dynamic sections move. Sections can move under fixed translation, rotation, conveyor motion, or sinusoidal motion.
    - Kinematics
      When you use kinematics to define the equipment, they will not move when a force provided by another element is applied.
    - Motion Controllers
      Unlike kinematics, you can add motion controllers to the geometry elements to allow objects to react to Particle-Geometry forces.
      - Specify a Force Controller
        You can add a Force Controller to a Geometry. This creates a force on the Geometry which will react to the forces acting on the Geometries from the contacts with particles. Force Controllers can be used to allow the Geometry to move based on gravity.
      - Specify a Torque Controller
        You can add a Torque Controller can be added to a Geometry. This creates a torque on the Geometry which will react to the forces acting on the Geometries from the contacts with particles. Torque Controllers can be used to allow the Geometry to move based on gravity.
      - Force and Torque Inputs as Equations
        The input fields for both torque and force can take equations as well as numerical values. These fields take equations in time, parameterized as 't', which can be used to create a wide-range of behavior.
    - Conveyors
      Conveyor motions are used to model systems containing conveyor belts. The Geometries themselves do not physically move as a result of this motion, but the particles in contact with them are moved based on the defined settings in this motion.
    - Parent-Child Functionality
      You can define Geometry sections as 'children' of another Geometry section owing to Geometry handling in EDEM.
  - Factories
    You can use Particle factories to define where, when, and how Particles/Meta-Particles appear in a simulation. The following types of particle factories are available - Static, Dynamic, Block, Volume Packing, and Recorded.
- Creator Tree-Environment
  Creator Tree-Environment allows you to define global settings for the simulation in the Environment section.
- Creator Tree-Physics
  Creator Tree-Physics allows you to add Physics interactions.

Specify a Force Controller

You can add a Force Controller to a Geometry. This creates a force on the Geometry which will react to the forces acting on the Geometries from the contacts with particles. Force Controllers can be used to allow the Geometry to move based on gravity.

To specify a Force Controller:

In the Creator Tree, right-click an existing Geometry and then select Add Motion.
Select Add Force Controller.
Optionally, click the icon.

Rename the Force Controller as appropriate and specify the following details:


For	Specify
Force Controller
Specification	Start Time Specify the point in the simulation at which the motion will begin.
	End Time Specify the point in the simulation at which the motion will end.
	Select the Loop Every checkbox to enable the kinematic to be looped. For example, a kinematic with Start time of Xs and End time of Ys with Loop Every set to Zs would run from Xs to Ys then repeat again at (X+Z)s to (Y+Z)s and again at (X+2Z)s to (Y+2Z)s until the specified Until Time is reached.
	Until Time Specify the time until when the kinematic will be looped.
	Force Equations Set an equation for the force. This can be a single value or an equation or an equation for more advanced behavior.
	Select the Include Gravity in Force Calculation checkbox to add a gravity force to the object. This is based on the mass of the section (and can be changed in the Mass section).
	Select a Damping Coefficient value from the Damping Coefficient list. Damping Coefficient is calculated by CmV, where C - Damping coefficient m - Mass of the object and V is the velocity of the object.
	Select the Constrain Motion Directions checkbox to constrain the motion in 1 or 2 dimensions. These dimensions are defined as a vector in the X, Y, and Z directions. Axis 1 and/or Axis 2 to constrain the motion in the directions the Geometries will be able to move.
	Select 1D or 2D to constrain the Geometry in one or two dimensions.
	Select Enable Speed Cap to specify the maximum speed value.
	Select the maximum Speed Cap value from the Speed Cap list to constrain the motion .
	Reference Space Select the Local or Global option to base the motion on the specific Geometry or the EDEM domain.

Warning: Using more than one controller of the same type during the same time in the simulation may result in unexpected behavior.
