Abstract/Summary Numerical modelling offers an outstanding opportunity to gain an understanding of the crustal dynamics and complex crustal system behaviour under various conditions. This presentation provides a long-term and ongoing effort on finite element based computational model and software development to simulate the highly coupled nonlinear interacting fault system, i.e. PANDAS-Parallel Adaptive Nonlinear Deformation Analysis System, which includes PANDAS/Pre and PANDAS/Post for the conventional pre-processing and post-processing before and after the simulation respectively, PANDAS/Thermo (for pure/coupled thermal analysis of metals and geomaterials), PANDAS/Fluid (for pure/coupled fluid flow in fractured porous media) and ESyS-Crustal (for simulating the interacting fault dynamics with/without coupling effects from such as thermal and fluid flow). A R- minimum strategy based finite-element computational model is proposed for modelling 3-dimensional nonlinear frictional contact behaviour between multiple deformable bodies with the arbitrarily-shaped contact element strategy to simulate interacting fault systems including crustal boundary conditions and various nonlinearities (e.g. from frictional contact, materials, geometry and thermal coupling). It has been successfully applied to large scale computing of the complicated nonlinear phenomena in the interacting fault system involving the nonlinear frictional instability, multiple material properties and complex geometries on supercomputers, such as the South Australia (SA) interacting fault system, South California fault model and Sumatra subduction model. It has been also extended and to simulate the hot fractured rock (HFR) geothermal reservoir system in collaboration of Geodynamics Ltd which is constructing the first geothermal reservoir system in Australia and to model the tsunami generation induced by earthquakes.
