Irazu Cloud simulation software
Posted by

Geomechanica is pleased to offer a cloud computing service, Irazu Cloud, for its Irazu simulation software, the innovative simulation package for modelling rock mass deformation and fracturing.

This service employs conventional software applications for model construction and post-processing, together with cloud computing for model execution. With this approach, you will build the Irazu models on your local computer using the Irazu Graphical User Interface, Geomechanica’s intuitive and easy-to-use pre-processing software. The models will then be submitted to the cloud for execution on Geomechanica’s computing infrastructure. As simulation outputs are generated, they will be automatically downloaded to your computer where visualization and post-processing can be carried out.

Main advantages of the Irazu Cloud include:

  • No need for specialized IT infrastructure: avoid the expense of purchasing a dedicated workstation for running models. To use Irazu Cloud, only a simple laptop (running Microsoft Windows or Linux) and an Internet connection are required.
  • Reduced capital costs: pay-as-you-go options are offered in lieu of a large upfront software licensing fee.
  • Greater flexibility: monthly, quarterly, and yearly subscriptions are available to better suit variations in your demand.
  • Improved accessibility: you can submit your models any time and from anywhere.
  • Automatic software updates: you are always running the most up-to-date version of our Irazu software.

To learn more about how you can use Geomechanica’s Irazu software, including a free, one-month trial subscription to Irazu Cloud, please get in touch with us by calling 1-647-478-9767 or emailing us at info@geomechanica.com. Subscribe to our mailing list to get the latest updates from us.

    Dear DR Lisjak:

    I am a PhD student of WuHan University, Hubei province, China. When I studied the FDEM codes, a question confused me very much. That is if when the interface elements (four nodes elements) are not removed (the fractures don’t emerge), the repulsive forces and the frictional forces between intact elements should be calculated? In your codes, it is done like this. But if the fractures have not emerge,the repulsive forces and the frictional forces may make the shear shtrenth of the material change, which based on the Mohr-Culomb failure criterion, and the quasi-static frictional forces should not be motivated. Hence, should the contact forces be calculated only when the interface elements between the contacting couples are removed? In other words, before fractures emerge, the forces between intact triangular element are calculated based on the cohesive interface elements, while after fractures emerge, the forces between contact couples are calulated based on the distributed contace forece penalty function method and the Coulomd-type friction law. But if we do so, the sudden change of the normal compressing force of the contacting couples beforce and after fracture would make a high velocity of the nodes, this is a new question. It is need to make the fracture penalty value and the contact penalty value match. More over, only one edge should take account of the contact forces if only one edge of a triangular element belongs a new fracture face, and the other two edges should take account of the cohesive forces due two the interface elements. I don’t know if I am right, and if I have make an expression easy to understand.

    Looking forward for your replay.Thank you very much.

    • Dear Hao, thanks for your interesting question. I believe there are two main reasons for computing the interaction forces (repulsive and frictional) using the element-element interaction algorithm even in the presence of an intact four-noded cohesive element. The first one is that the mechanical response of the interface in compression is much smoother as there is no temporary loss of repulsive forces once a cohesive element breaks. The second one is that frictional forces in the interaction algorithm are mobilized over a sliding distance and therefore it is better to include these forces before the failure of a cohesive element (to avoid the temporary loss of frictional resistance).

    Dear Dr Lisjak:
    I’m a PhD student from Tsinghua University, China. I’m very interested in FDEM. I plan to use this software as a tool to solve problems and do further research. How can I get Irazu simulation software and the Irazu Cloud and how can I use Geomechanica’s Irazu software, including a free subscription to Irazu Cloud or user guide?
