Why Choose FLAC2D?

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
