Introduction
This intermediate tutorial is directed at users who have covered introductory exercises,
as the initial set-up of simulation is abbreviated and basic functionality not explained in
detail. In case of any uncertainties or problems, refer to previous tutorials or EDEM Help
section.
This exercise explores further options of EDEM, focusing on the use the internal bonded
particle model.
The main concepts are:
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. Bonded_Particle_setup.dem) and click Save.
5. Remember to often press Save when setting up the simulation.

3. Set the Name, Poisson's ratio, Shear modulus and Density as shown below:
4. Click the
button in the Interaction section. This will automatically define the
interaction between elements both made of new material 1, as no other material has
been created. Set the coefficients as follows:

on the toolbar.
2. Set the Fixed Time Step lower box to 5e-5 s, which would be about 29% of Rayleigh
time step.
2. Click the Refresh Viewer button at any point to update the Viewer and see how the
simulation is progressing.

8. In the Domain section at the top, uncheck Auto Update from Geometry box and set
the domain as follows:
The geometry should now look like the image below, with the rectangle open at one end
and the loading plate above the unsupported end of the particles.

on the toolbar.
2. Set the Fixed Time Step lower box to 2e-5 s, which would be about 12% of Rayleigh
time step.
2. Click the Refresh Viewer button at any point to update the Viewer and see how the
simulation is progressing.
