Why Choose FLAC3D?

POWERFUL

  • Numerical stability with large displacements, including collapse
  • 64-bit architecture allows very large models to be constructed
  • 21 built-in material constitutive behaviors; more available with options
  • P2PSand for 3D dynamic and liquefaction analysis is included
  • Complex materials and pore pressure distributions
  • Assess service limit state criteria
  • Automatic factor-of-safety analysis
  • Coupled or uncoupled groundwater flow comes standard
  • FISH scripting language enables you to access, monitor, and control nearly every model and solution parameter
  • Python scripting provides the access to most model elements and a vast array of Python mathematical, engineering, and scientific libraries.
  • Optional dynamic, thermal, creep solution analyses and C++ plug-ins for custom constitutive models and function libraries
  • Built-in text editor
  • Building Blocks pane provides tools for interactive 3D model construction and meshing
  • Model pane to:
    • select model zones, faces, and structural elements which allows easy assignment of groups that can be used to define regions and boundaries,
    • specify interfaces,
    • quickly define liner structural supports, and
    • assign constitutive models and material properties.
  • Extrusion pane is a user interface for constructing 3D models from 2D sections; this pane integrates with Building Blocks for full 3D manipulation
  • Socket utilities permit models to be coupled to another instance of FLAC3D or 3DEC (requires 3DEC license) and to third-party software
  • PFC3D 6.0 is now available as a module, permitting Distinct Element Method (DEM) objects (balls, clumps, and walls) to be used directly within the FLAC3D framework (requires PFC3D license)
  • Every event that modifies the model state is recorded; allowing for undo, playback, or reuse of any or all previous modeling work

EFFICIENT

  • Multi-core processing (mechanical calculations)
  • Multi-core processing (FISH, fluid-flow, attach-logic, and thermal-option) NEW
  • Optimized solution algorithms (structural element calculations 10% faster NEW and constitutive model calculations, on average, are 70% faster NEW)
  • Customize efficient material constitutive behaviors (requires C++ Plug-in option)
  • Customize fast library functions (DLL) that can be loaded and run as needed (requires C++ Plug-in option)

PROVEN

  • Tested and validated against analytical solutions
  • Sold commercially for over 25 years (since 1994)
  • Used by Itasca’s own consultant engineers and scientists on civil, mining, and energy projects
  • Large repository of examples and validations, with 1000’s of published articles and conference papers
  • Thousands of licenses used worldwide by industry, universities, and government agencies

RELIABLE

  • Realistic physical solutions
  • Natural evolution of failure
  • Transparent methodology with all equations and algorithms fully documented
  • Built-in constitutive models are open-source; no black boxes
  • Live, person-to-person software support provided by experienced engineers and software developers
  • Extensive manuals and documentation
  • Automated software update notification in the event of any bug fixes

FLEXIBLE

  • General by design
  • Access to almost all internal variables via the embedded FISH scripting and Python languages
  • CAD interoperability (import DXF and STL geometry)
  • Import ABAQUS and ANSYS meshes
  • Import and export data using I/O functions and from tables and charts directly as CSV files
  • Users may create and run their own constitutive models using FISH scripting or the optional C++ Plug-in
  • The standard version is portable between users and computers
  • A multiple seat network version also is available
  • Licenses are available in-perpetuity or as a monthly or annual lease
  • Options may also be leased

ECONOMICAL

  • No CPU limits or additional CPU fees
  • No annual maintenance fee
  • Coupled or uncoupled steady-state and transient fluid flow is included
  • 21 constitutive models, including Hoek-Brown, Plastic Hardening, NorSand, and P2PSand are available for no additional fees
  • Free standard technical support and software updates (see EULA)
  • Discounted pricing for qualified academic institutions
  • Two instances of FLAC3D can be run on a single computer with the standard version
  • The standard version is secured using a USB key which is portable between users and computers
  • Network licenses are available to share within an organization
  • Advance purchase of the next version (pre-purchase) at a discount is available at all times
