The Underground Research Laboratory (URL) was a revolutionary test site in Canada operated by Atomic Energy of Canada Limited (AECL) from 1985-2003 to study deep geological repositories for nuclear waste. Perhaps the most cited study from the URL is by Martin (1997) documenting the observed excavation damaged zone (EDZ) of a 3.5-m-diameter Mine-by Experiment (MBE) … Read more
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 are very proud to unveil PyIrazu, a Python module that was developed to interface with Irazu! The goal of PyIrazu is to provide Irazu users a means of manipulating and running input files without relying on the user interface. With PyIrazu, operations such as changing, adding, and/or removing material property sets can be done … Read more
In Irazu version 6.1, a new elastic FEM material model has been added to grant the ability to explicitly define unfracturable domains within an FDEM model. Ultimately, this leads to significantly reduced simulation run times without compromising the accuracy of the result. In addition, we would like to provide a sneak peek of new elasto-plastic … 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
