With the official release of Irazu 6.2, we are excited to share some of the new features we have been working on over the past year! These new features improve the overall modelling workflow, simplify post-processing of results, and unlock new advanced modelling capabilities. We can’t wait for our users to experience Irazu 6.2 first-hand! … Read more
We recently hosted a webinar to provide an overview of the latest features of Irazu version 6.1 in action. We also demonstrated two practical applications of Irazu, including a slope stability problem using the new time-varying, user-imported water table profiles, as well as a tunnel excavation model with mixed FEM and FDEM material models. For … Read more
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
Following up from our previous blog post on 3D FEMDEM Simulations, 3D simulations of a tunnel excavated in a weak rock (resembling properties of a clay shale) are presented here (E=3.8 GPa, ν=0.25, σt=0.41 MPa, c=5 MPa). In this simplified case study, the entire length of the tunnel was excavated at once at the beginning … Read more
We have been working on a prototype of three-dimensional FDEM. We’ve implemented most of the critical features into the code, including a quasi-static friction law, Mohr-Coulomb failure criterion, and transversely isotropic elastic constitutive law. We’re excited to showcase some of the simulations results here. The figure below shows the simulation of a uniaxial compression test … Read more
