EASE-OF-USE

• Interactively create models from CAD files (DXF, STL), geometry sketching, or images
• Automatic structured and unstructured mesh generation
• Skinning to automatically identify model boundaries to set boundary conditions
• Interactively assign groups, constitutive models, and properties/distributions
• Built-in database to save/import/export material properties
• Automatic stress initialization
• Intuitive commands are easy to learn
• Most UI interactions are automatically translated into commands, which can be saved to a datafile and re-used
• Built-in help / command auto-complete
• Advanced built-in text editor makes creating and running models simple
• With Version 9’s common UI, seamlessly move between programs or easily couple to other licensed (or demo) Itasca software

FASTER

• Multi-threaded to utilize the full power of your computer for faster solutions
• Multi-threaded FISH Lists and Operators to query or modify the model incredibly quickly, even while cycling
• New Maxwell damping for 10-200x faster performance for dynamic models
• FLAC2D plane-strain or axisymmetric models run up to 2-5x faster than equivalent FLAC3D models
• New, faster implicit solvers for fluid flow and thermal calculations

POWERFUL

• Large-strain simulations to capture the full extent of model deformation
• Mixed and Nodal Mixed Discretization (NMD) for accurate plasticity calculations
• Includes over 20 built-in constitutive models for soil, rock, and concrete
• Built-in liquefaction models P2P-Sand and NorSand with PM4Sand, PM4Silt, and UBCSAND liquefaction models coming
• Advanced plotting tools to understand model results and for working with hundreds of plots on real projects
• FISH, Itasca’s scripting language, provides you with unparalleled control over, and customization of, the model
• Built-in Python 3.10 scripting includes SciPy for plotting, NumPy for computing, and Pyside for UI customization
• Statistical generation tools for Discrete Fracture Networks (DFNs)

FLEXIBLE

• Highly customizable UI and modeling
• All licenses permit two instances of FLAC2D to be run on the same computer
• Store custom model data via “Extra” variables, for nearly all model elements, that can be read, written to, and plotted
• Import and export any ASCII data format
• Optional user-defined constitutive models (UDM) can be written in C++ using Visual Studio template
  

ANALYSES

• Plane-strain
• Axisymmetric
• Static stability
• Dynamic (option) stability
• Automatic factor of safety analysis (shear strength reduction method)
• Back-analyze failure and calibrate forward-prediction
• Service limit state (SLS) and ultimate limit states (ULS) based on displacements
• Zone relaxation simulates gradual excavation for construction sequencing, , including out-of-plane excavation
• Simulate material damage, and failure
• Effective stress using conventional or complex pore pressure distributions
• Fluid flow (single-phase)
• Seepage and consolidation
• Model ground support correctly with coupled ground-structure interaction (beams, cables, piles/rockbolts, and liners are available)
• Simulate discontinuities (faults, joints, bedding planes, and construction boundaries) using interfaces; capture yielding or failure, shear displacements, opening, and closure along them
• Static liquefaction
• Dynamic (option) liquefaction
