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, where each particle has a predefined set of properties. The system further has an interface for receiving at least one behaviour model for applying to the particles, and supports receipt from the at least one model of one or more custom properties for the particles. The system is responsive to receipt of the one or more custom properties to extend the discrete elements to contain both the predefined set of properties and the one or more custom properties for the particles. The system is operable to perform a simulation using discrete element modeling by applying the at least one behaviour model to the particles and to update accordingly values of the predefined and custom properties. The values of the custom particle properties are stored with the default (built-in) particle property values and can be analysed and visualised in the same way as the default property values.
