If you are interested in planning and purchasing a customized software training course, please contact your local agent. Instruction is available either at Itasca or at the client's location. The training courses are designed to fit individual user needs and experience. ITASCA offices regularly organize customized training courses for their clients. Itasca will host introductory training courses in Europe: To pre-purchase FLAC3D 6.0 and obtain the PH model, please contact your regional software sales representative. Remember that the new Plastic Hardening Model for Soils is already available for FLAC3D 5.0 users, upon request, when they pre-purchase FLAC3D 6.0. FLAC3D Plastic Hardening Model for Soils.A presentation on using Python scripting in PFC is now available for you to on our website and on YouTube.

In update 21, a rolling resistance model and a Burger’s model have been added to the list of built-in contact models, to widen the range of applications that can be investigated with PFC out of the box.įrom update 20, not only can you control PFC entirely via Python files and/or the IPython console, you can also make custom plots using matplotlib, undertake effiient computations using array expressions with NumPy, undertake a myriad of custom computations with SciPy and also create custom GUI panes directly within PFC using PySide. Pre-order FLAC 8.0 today from your regional sales representative and get the best price when upgrading from FLAC 7.0. A « Walk-through » document describes in detail each step of the modeling procedure. These examples are intended to demonstrate the various classes of problems to which Itasca software may be applied. More than that we now propose « Software Examples » web page to help Itasca software users to become familiar with their software.

Pore pressure contours (after 50 years)įLAC 8.0 is due to be released later this year and if you have pre-purchased FLAC 8.0, you are automatically entitled to download and try the FLAC 8.0 Beta software.
Plastic zones around the gallery (end of excavation)įigure 2. The evolution of the system can be separated in two phases: the excavation phase which can be considered as an undrained system due to low clay permeability and EDZ development (figure 1) and the ventilation and filling phase during which ventilation variations and suction effects have a significant influence on the transient behavior and a strong positive effect on the stability of the gallery (figure 2)įigure 1. In the framework of this study, Itasca France has developed a coupling method between FLAC and TOUGH2 to model the hydro-mechanical conditions in the repository near-field under partially saturated conditions, before and after waste emplacement in the Opalinus Clay formation. To make the better choice, they have to assess the evolution of the L/ILW and the HLW cavern near-fields, for various conditions. NAGRA is proposing to study siting regions for the disposal of L/ILW (Low- and Intermediate Level Waste) and of HLW (High-Level Waste). Observed spalling failure in ventilation shaft (left) and yielding in calibrated model (right) This work will be presented in detail in the upcoming symposium on Design Methods in Underground Mining, in Perth, Nov 17-19. Only the brittle material model could capture the shape and extent of observed spalling, as shown below. The initial part of this work involved calibrating the material model parameters against observed spalling failure in a ventilation shaft in Malmberget.
The results are to be used as a basis for design decisions regarding the future new main haulage level at the Malmberget Mine. All the modeling was conducted using FLAC with input stresses obtained from a mine-scale FLAC3D model. A brittle (cohesion-weakening, friction-strengthening) material model was used, and a range of different parameters, including location, orientation and rock mass strength, was analyzed. Itasca Consultants AB (Sweden) has conducted a study on optimal ore pass orientation, with respect to stress orientations, for the LKAB Malmberget Mine. All news about software developments and consulting is available on the web site. We invite you to visit our all-new website to give us your feedback. To be more accessible and more readable, the ICG website has been refreshed too. Python scripting is now integrated into PFC 5.0 and the new Plastic Hardening Model (available in FLAC 8.0) is offered for FLAC3D 5.0 users who pre-purchase FLAC3D 6.0. The summer was an eventful period for Itasca since FLAC 8.0 is now feature complete. European Newsletter 3rd quarter 2015 Consulting
