Grasselli's Geomechanics research group is doing extensive research in the field of numerical modeling of rock mechanics / mining problems using the combined finite-discrete element method (FEM/DEM). This includes modeling a wide variety of problems ranging from laboratory-scale tests, e.g., Brazilian disc test and triaxial tests, to block caving, toppling, block fall, etc.

Graphical User-Interface for the 2D FEM/DEM code

To make the 2D version of the FEM/DEM code more user-friendly a Graphical User-Interface (GUI) was developed by Omid K. Mahabadi.

You can obtain the GUI through our download page. Please read the system requirements and the disclaimer of the GUI carefully. If you plan to use the GUI, it has to be cited as:

Note for the GUI users:
If the default decimal point (or decimal separator) of your system is ',' (i.e., a comma) you have to change it to '.' (i.e., a point). To do this go to Control Panel --> Regional and Language Options. In the Regional Options tab, click on Customize and then change the Decimal Symbol to a point ('.').
