Why Choose FLAC?

POWERFUL

  • Numerical stability with large displacements, including collapse
  • Very large models (64-bit)
  • 19 built-in material behaviors; more available with options
  • Automatic factor-of-safety analysis
  • Coupled or uncoupled groundwater flow
  • Optional dynamic, thermal, and creep solution analyses
  • Solution analyses can be coupled to the mechanical analysis within FLAC
  • Models can be be coupled to another instance of FLAC or to PFC2D (requires PFC2D license)
  • Complex materials and pore pressure distributions
  • Assess service limit state criteria
  • Scripting with FISH to access, monitor, and control nearly every model and solution parameter
  • Customize constitutive models using FISH
  • Customize constitutive models using optional C++ User-Defined Models (UDM)

EFFICIENT
