Overview

The 3D coupled Finite-Discrete element analysis tool (3D coupled FE-DE) has been developed by the geotechnical research group at McGill University. The framework allows for the simulation of interaction between FE and DE domains. Conventional FE and DE analyses can also be performed using this tool. The developed framework is implemented in YADE, an open source code for the DE analysis. Since both FE and DE simulations are handled in a common package, the tool provides an efficient approach for solving coupled FE-DE geotechnical engineering problems.
The computational parts of the coupled FE-DE framework are written in C++ with object oriented approach. Scripts are built using Python, which assures rapid and flexible simulation construction. Users who do not wish to modify C++ engines can develop their own analyses using Python scripts.
