The paper reports on creation of analogue models of structures in virtual reality, using an emergent, or bottom-up approach, inspired by laws of Complexity. This approach focuses on component based modelling using fundamental laws of physics. The creation of system models is then achieved through interaction of the components, from the bottom-up, leading to(More)
The Discrete Element Method (DEM) is a numerical model to describe the mechanical behaviour of discontinuous bodies. It has been traditionally used to simulate particle flows (e.g. sand, sugar), but is becoming more popular as a method to represent solid materials. The DEM is very computationally expensive, but has properties that make it amenable to(More)
The Distinct Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles, and is widely used for process optimization in the food and pharmaceutical industries. The DEM is very computationally expensive, but has properties that make it amenable to acceleration by reconfigurable computing. This(More)
The Discrete Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles. They can be bonded together to represent rock or remained unbonded to represent soil. The DEM is computationally very expensive, but can benefit from the properties of reconfigurable computing. This paper presents the design(More)
