Research effort is currently focussed on bringing new numerical tools to bear on gaps in understanding. First, problems associated with the fractured subsurface - for Geological disposal of radioactive waste and for geothermal energy development. Second, problems of multibody particulate systems - for natural granular matter, coastal structures, and industrial technologies such as catalysts.
The Open Source tools and their applications were recently launched on the Solidity website for the application of Discontinuum Modelling to fracture, fragmentation and granular processes, and their coupling with fluids and thermal fields by code developer colleagues in AMCG has produced remarkable realism in a number of complex fracturing and particulate processes.
specific areas of research include:
- Generic discontinuum modelling capability: fracture, fragmentation/blasting, granular and solid-fluid coupled process modelling.
- Fracture networks, hydro-geomechanical coupling and flow in reservoir rocks.
- Stability of rubble-mound breakwaters and coastal structures under wave action.
- Effect of particle shape on packing.
