By Jacob Andersen, CEO NaturaFrac Inc. In the ever-evolving field of geomechanics, collaborations between industry leaders are pivotal in driving technological advancements. NaturaFrac’s work with Geomechanica exemplifies how synergistic efforts can lead to significant innovations in rock fracturing technology development. For almost every project with Geomechanica, Dr. Andrea Lisjak (numerical modelling lead and co-founder) has … Read more
Irazu version 6.1 has launched and there are several new and exciting features that have been implemented including: Elevation-varying water table (Irazu 2D) A new hydraulic boundary condition has been added to Irazu 2D Hydro, granting the capability to impose elevation-varying hydrostatic fluid pressures to a model. In addition, the water table can be temporally … 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
