Discrete element method (DEM) is a numerical method for computing the motion and interaction of a large number of small particles. DEM is an effective method of addressing engineering problems in granular and discontinuous materials, especially in granular flows, powder mechanics, and rock mechanics. Calibration means the determination of parameters governing the mechanical interaction of the individual particles and walls making up discrete element (DEM) models. Since the elaboration of DEM, calibration is the most difficult part of the DEM modeling process. Our goal is to develop efficient numerical algorithms for the automatic determination of the optimal micromechanical parameters governing the mechanical behavior of granular material assemblies.

The aspirant must have solid programming knowledge for developing the autonomous calibration and optimization algorithm. High level knowledge of advanced dynamics and computational modeling is also expected.
