An Introductory webinar to Irazu by Geomechanica, available through the Altair Partner Alliance. Irazu is a versatile 2D/3D finite-discrete element software package for the analysis of large deformations, fracturing, and stability in rock masses. The integration of various multiphysics solvers and advanced features into a single software package enables Irazu to be used for a wide range of engineering applications, including but not limited to excavations, slope stability, tunneling, dynamic analysis, mining, and reservoir geomechanics. Irazu comes with extensive tutorial, theory, and verification manuals.
