    Introduction

    Embark on a journey into the realm of three-dimensional (3D) nonlinear geomechanical numerical models, featuring Itasca’s powerful tools 3DEC and FLAC3D. In the pursuit of optimized designs and solutions to complex challenges posed by irregular geometries, geological structures (e.g., dykes, faults), varying stress regimes, and complex scale-dependent constitutive behavior of rock masses, these advanced models become indispensable.

    As the demand for advanced numerical modeling in ground-structure interaction analysis grows, it becomes crucial to choose the right modeling tool, represent geometries with high-quality meshes, select the most representative constitutive model, and interpret results with precision. However, mastering these fundamental aspects through self-learning or relying solely on extensive tool documentation can be overwhelming, time-consuming, and, in many cases, impractical. This course serves as a guide, offering a practical understanding of the advanced numerical modeling process in FLAC3D and 3DEC. The focus extends to leveraging the FISH programming language embedded in these programs, along with creating intricate geometries using Rhinoceros and Griddle.

    Gain the insights needed to navigate the complexities of advanced numerical modeling, ensuring a solid foundation for safer designs. This course is tailored to provide an effective and efficient learning experience, particularly beneficial for those new to the world of modeling.
