Why Choose 3DEC?

POWERFUL

  • Both continuum and discrete model simulations possible
  • Numerical stability with large displacements, including collapse
  • Build very large models (64-bit)
  • 12 built-in material behaviors and 8 creep constitutive models
  • 6 built-in joint models
  • Automatic Factor of Safety analysis
  • Capable of groundwater flow, including flow through joints and groundwater matrix (i.e., permeable solids) fluid-flow between fractures
  • Proppant simulation in fluid-filled joints
  • Coupled mechanical-hydro-thermal solutions possible
  • Accommodate complex materials and pore pressure distributions
  • Assess service limit state criteria
  • Create custom functions using FISH or Python
  • Perform thermal and dynamic analyses (options)
  • Customize material behaviors efficiently using optional C++ User-Defined Models (UDM) for both zones and joints (option)

EFFICIENT

  • Multi-core processing
  • Optimized solution calculations
  • Multi-threaded FISH scripting
  • Customize material behaviors efficiently using optional C++ User-Defined Models (UDM)

RELIABLE
