FEM Solver
Posted by

The computational engine of Irazu simulation software is based on the finite-discrete element method. This inherently means that Irazu is equipped with a finite element solver (FEM). The FEM solver uses linear elastic constitutive laws (isotropic and transversely isotropic) and solves the equations of motion using an explicit time integration scheme. Therefore, it is well Read More >>>



 
Video demo of Irazu to simulate hydraulic fracturing
Posted by

Irazu is an advanced general-purpose rock deformation and fracturing simulation software. In this video, an application of Irazu to simulate fluid injection into a permeable, fractured rock mass is presented (i.e., hydraulic fracturing). The software is capable of capturing: fluid-driven fracturing of intact rock; energy dissipation due to fluid viscosity and fracture toughness; fluid leak-off Read More >>>



 
A new fully-coupled hydro-mechanical formulation for the Irazu software
Posted by

We are excited to announce that we have been working on the introduction of hydro-mechanical (H-M) coupling in our Irazu FDEM software. The introduction of H-M coupling arguably makes the Irazu software one of the most sophisticated simulation software currently available for geomechanical applications as a multitude of multi-physics processes can be taken into account, Read More >>>

Geomechanica is launching a guest blog series, written by experts and numerical modellers in the field of rock engineering. In the first post of this series, we’re showcasing the work of Andrés Alcolea on “A pragmatic methodology to abstract the EDZ around tunnels of a geological radioactive waste repository – Application to the HG-A experiment Read More >>>



 
ISRM Congress 2015: One-day course on rock fracturing simulation using Irazu FEMDEM software
Posted by

Geomechanica is looking forward to teaching a short course on the application of the hybrid finite-discrete element method (FEMDEM) to simulate fracture processes in rocks at the 13th International Congress on Rock Mechanics . The one-day course , instructed by Dr. Andrea Lisjak and Dr. Bryan Tatone, will be held at the Palais des Congrès Read More >>>



 
Geomechanica’s new Irazu simulation software for modelling geomaterials
Posted by

Modelling the deformation and failure process of rock represents a challenging task due to the intrinsic characteristics of the rock material and the presence of natural discontinuities. To address the modelling challenge, Geomechanica has been developing Irazu, an innovative software package based on the hybrid finite-discrete element method (FEMDEM or FDEM), which combines conventional continuum Read More >>>



 
Workshop on Simulation of Fluid-Driven Fracture Propagation
Posted by

Numerical simulation of fluid-driven fracture propagation is a subject of great scientific, industrial and societal interest. A two-day workshop has been organized by the Eindhoven Multiscale Institute of the Eindhoven University of Technology (Netherlands) to be held on April 8-9, 2015. The workshop assembles several of the most prominent researchers in this exciting field to Read More >>>
