Itasca Flac3D 9.1
Itasca FLAC3D (3D Fast Lagrangian Analysis Code) is a high-end three-dimensional numerical analysis program developed based on continuum theory and explicit finite difference methods, widely used in geotechnical and mining engineering analysis and design. It is particularly suitable for addressing complex geotechnical issues that are difficult to solve using the finite element method (FEM), such as complex multi-condition scenarios, large deformations, nonlinear material behavior, and the occurrence and development of instability and failure. FLAC3D fundamentally inherits the computational principles of the FLAC program and further extends its analytical capabilities into three-dimensional space. The algorithmic background, professional theory, and sequential inheritance relationship with the target industry determine that Itasca FLAC3D generally inherits the advantageous technical features of the FLAC program.
