| 20110032255 | METHOD AND APPARATUS FOR DISCRETE ELEMENT MODELING WITH A VIRTUAL GEOMETRY OBJECT - One embodiment of the invention provides a computer-implemented method for discrete element modelling of a plurality of discrete elements corresponding to particles and physical geometry elements. The modelling performs a simulation through time of physical interactions of the particles with each other and with the physical geometry elements in a three-dimensional space. The method comprises providing a virtual geometry object comprising a user-defined shape. The virtual geometry object does not undergo physical interaction with the particles or physical geometry elements during the simulation. The method further comprises receiving user-defined parameters for determining the position, orientation and any movement of the virtual geometry object with respect to the three-dimensional space. The method further comprises locating the virtual geometry object in the three-dimensional space during the simulation in accordance with the user-defined parameters and identifying the particles, physical geometry elements and/or physical interactions having a particular relationship with respect to the virtual geometry object. The identified elements can then be analysed by the user, for example to determine the number of particles located at a given time within a specific region of the simulation space (as defined by the virtual geometry object). | 02-10-2011 |
