Abstract: One embodiment of the invention provides a computer-implemented simulation system for discrete element modeling. The system comprises discrete elements corresponding to objects or particles, each particle having a predefined set of properties. The system further has an interface for receiving at least one behaviour model for applying to the particles, and for receiving from the at least one model, one or more custom properties for the particles. In response to receiving a custom property, the system extends the discrete elements to contain both the predefined set of properties and the custom property for the particles. The system performs a simulation by applying the at least one behaviour model to the particles and updating values of the predefined and custom properties. The values of the custom particle properties are stored with the default particle property values and can be analysed and visualised in the same way as the default property values.

Abstract: 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.

Abstract: 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.
