20140039858 | METHOD AND APPARATUS FOR DISCRETE ELEMENT MODELING INVOLVING A BULK MATERIAL - Computer-implemented methods and systems are described for discrete element modelling of a plurality of discrete elements corresponding to particles and physical geometry elements. The disclosed embodiments provide a plurality of discrete element material models, each discrete element material model corresponding to a respective bulk material and containing (i) information regarding the properties of particles within said bulk material, and (ii) information regarding the behaviour of interactions between such particles. The following information can be received from a user: a selection of a bulk material for use in a simulation, and a specification of properties associated with the selected bulk material. The disclosed embodiments can perform a discrete element model simulation on a set of particles, wherein the simulation uses the information regarding the behaviour of interactions between particles from the discrete element material model for a user-selected bulk material. | 02-06-2014 |

20130332127 | METHOD AND APPARATUS FOR DISCRETE ELEMENT MODELING WITH A VIRTUAL GEOMETRY OBJECT - A method is described for discrete element modelling and for performing a three-dimensional simulation through time of a plurality of discrete elements corresponding to particles and physical geometry elements. The method can comprise the following operations: 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); receiving user-defined parameters for determining the position, orientation and any movement of the virtual geometry object with respect to the three-dimensional space; locating the virtual geometry object in the three-dimensional space during the simulation in accordance with the user-defined parameters; and/or 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. | 12-12-2013 |

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 |
