3DEC 9 Officially Released
ITASCA introduces 3DEC v9: Advanced modeling solutions for addressing challenging geomechanical problems in three-dimensional analyses of rock, soil, concrete, nonlinear structural ground support, and groundwater flow.
MINNEAPOLIS, MINNESOTA – January 23, 2024 – ITASCA has announced the release of 3DEC v9, an advanced hybrid discontinuum and continuum modeling tool designed to solve even the most difficult geotechnical challenges in mining, civil, and energy engineering.
3DEC v9 builds on over four decades of ITASCA's expertise in geomechanical software research and development. As a part of ITASCA's suite of industry-standard software products, which includes FLAC3D, FLAC2D, UDEC, PFC Suite, XSite, MassFlow, MineDW, and Griddle, this release is tailored to address geomechanical engineering issues in slope stability, underground excavation, tunneling, ground-structure interaction, and earthquake simulation.
3DEC v9 offers a significant performance boost, with speeds up to 10 times faster than its predecessor. This version introduces advanced computational modeling techniques, an upgraded user interface, enhanced Python support, and compatibility with partner products. The software now supports additional constitutive models, such as concrete, Von Mises, and Columnar Basalt, bringing the total number of supported constitutive models to 18. Notably, this version includes improvements to bonded block modeling (BBM), which is now both faster and easier. The contact detection between blocks enables sliding, opening, closure, rotation, and even complete separation, accompanied by improved joint logic.
According to Jim Hazzard, ITASCA's Director of Product Development, "3DEC v9 enhances both the capabilities and performance of geomechanical modeling. It serves as a powerful geomechanical analysis tool meticulously crafted to fulfill the needs of today’s engineers, offering a comprehensive set of robust modeling methods and strategies."
Delving into the enhanced features, Hazzard explains, "Significant improvements have been made to calculation efficiency so that models will reach a steady state solution significantly faster, dynamic timesteps will be noticeably larger, and plotting is much more responsive."
"The incorporation of nonlinear structural elements and a dedicated constitutive model for concrete in 3DEC v9 facilitates the simulation of intricate ground-structure interactions. This capability enables a more authentic assessment of performance and failure mechanisms, enhancing the capacity of civil engineers to simulate geotechnical conditions that mirror real-world projects."
Charles E. Fairhurst, CEO of ITASCA International Inc. (III), states, "3DEC v9 integrates the most recent advancements in geomechanics computational modeling, featuring optimizations that enhance performance and robustness. With improved usability and computational methods, this empowers engineers in the field, enabling them to address geomechanical problems—ranging from mundane to challenging—with speed and ease."
3DEC v9 is built upon a common framework, meaning that it shares a common look and feel with other ITASCA software, as well as many common components (e.g., structural elements, constitutive models, discrete fracture networks). 3DEC v9 also enables built-in mechanical coupling with FLAC3D, streamlining complex engineering modeling, reducing overhead, and simplifying project management. This results in a potent modeling suite that simplifies work across a broad spectrum of engineering simulations.
3DEC Version 9 is now available for purchase for Windows and Linux. For more information, including detailed product features, pricing, and licensing options, visit https://ItascaSoftware.com/products/3dec/.
