DEM 是世界上第一个用现代化离散元模型科技设计的用来模拟和分析颗粒处理和生产操作的通用CAE软件,通过模拟散状物料加工处理过程中颗粒体系的行为特征,协助设计人员对各类散料处理设备进行设计、测试和优化。[1] EDEM主要由三部分组成:Creator、Simulator和Analyst。Creator是前处理工具,完成几何结构导入和颗粒模型建立等;Simulator是求解器,用于模拟颗粒体系的运动过程;Analyst是后处理模块,提供了丰富的工具对计算结果进行分析。

EDEM Tutorial: Conveyor
Page 2 of 14
Introduction
This tutorial describes how to set-up and analyze an EDEM simulation. The model is
a conveyor belt used to transport material. The tutorial highlights the use of particle
templates, the Moving Plane contact model, and how to create bin groups.
1. Start EDEM.
2. Go to File > Save As…
3. Select a location on the local
machine (e.g. C:\EDEM_Tutorials).
4. Enter a file name (e.g.
Conveyor_Tutorial.dem) and click
Save.
EDEM Creator: Setting up the model
Step 1: Set the Global Model Parameters
Choose the units and name the model
The first step in creating the model is to set the units used throughout EDEM.
1. Go to the Options > Units menu.
2. Change the following measurement units:
Angle to degrees (“deg”)
Angular acceleration to deg/s
2
Angular velocity to deg/s
Length to mm
Mass to kg
Mass Generation Rate to kg/s
3. On the Globals tab in the Tabs pane, enter the title 'Conveyor Model' in the Title
field in the Simulation section.
