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.
Mahabadi OK, Grasselli G, Munjiza A, 2010, Y-GUI: A Graphical user interface and pre-processor for the combined finite-discrete element code, Y2D, incorporating material heterogeneity. Computers & Geosciences, Volume 36, Issue 2, February 2010, Pages 241-252. DOI: http://dx.doi.org/10.1016/j.cageo.2009.05.010
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 ('.').
