Despite the insight gained from 2D particle models, and given that the dynamics of crustal faults occur in 3D space, the question remains, how do the 3D fault gouge dynamics differ from those in 2D? Traditionally, 2D modeling has been preferred over 3D simulations because of the computational cost of solving 3D problems. However, modern high performance(More)
Solid earth systems simulation is now becoming feasible from the microscopic to the global scale. The ACES international cooperation has shown development of simulation capabilities for solid earth phenomena that are beyond the ability of a single group or country. Each country has different strengths, computational approaches, and laboratory and field(More)
We present the development of an active optical cable (AOC) for the Camera Link interface, in which our compact optical assembly structure has been applied. The optical Camera Link cable enables the transmission of a high resolution image more than 10 m which has been the maximum transmission length for conventional metal cables.
The Discrete Element Method (DEM) is a popular particle-based numerical method for simulating geophysical processes including earthquakes, rock breakage and granular flow. Often simulations consisting of thousands of particles have insufficient resolution to reproduce the micromechanics of many geophysical processes, requiring millions of particles in some(More)
A realistic numerical simulation model for all physical processes underlying the earthquake phenomenon on HPC's would provide a powerful tool to study fault behavior and earthquake nucleation. The microphysical particle-based Lattice Solid Model (LSM) currently being developed at QUAKES provides a basis on which to construct such a model. Presently, the(More)
