Geomechanical Simulation Software

A more complete understanding of the evolution of a rock mass or geomaterial under stress is provided through the combination of observations from seismic and microseismic monitoring with fully controlled geomechanical models. The capability of predicting the rock mass response to applied stress changes allows the optimization of engineering operations so that costs and risks are minimized. Geomechanica (http://www.geomechanica.com) develops Irazu: a versatile 3D and 4D geomechanical simulation package based on the finite-discrete element method (FDEM). A distinctive feature of Irazu is the ability to explicitly capture fracture and fragmentation processes in brittle geomaterials, without any a priori assumptions regarding the failure mode or failure path. Thus, complex, non-linear behaviour can be captured numerically. Irazu's key features (http://irazu.geomechanica.com):

• Precise simulation of deformation and fracturing in geomaterials in petroleum, mining and civil engineering applications
• Fully-coupled, multi-physics and multi-scale capabilities
• Consideration of rock mass discontinuities via Discrete Fracture Network (DFN) capabilities
• Interactive modelling of pre-existing rock mass discontinuities and new fractures
• High computational speed due to innovative GPU-based parallel algorithms
• Realistic incorporation of rock mass fabric features, including bedding planes, joints, heterogeneities and anisotropies
• Synthetic seismicity
• Flexible licensing, including standalone licences and cloud subscriptions
