Software Products

The latest updates to ITASCA software products such as FLAC3D, FLAC2D, 3DEC, PFC, and MassFlow now include point releases (e.g., 9.1, 9.2) between major versions (e.g., 9.0, 10.0). These point releases bring significant benefits, especially for subscription license holders.

Subscription license holders enjoy seamless access to point releases at no additional cost. These point releases are packed with new features and capabilities developed in response to user feedback and industry advancements. By staying current with point releases, subscribers can leverage the latest tools and functionalities, enhancing their productivity, efficiency, and competitiveness.

Perpetual license holders also benefit from continuous support within their software version's support period. While they may not receive point releases, they still qualify for bug fix updates and minor improvements, maintaining stability and reliability in their software environment.

Applies to FLAC3D, FLAC2D, 3DEC, MassFlow, PFC3D, and PFC2D:

• New UI object tree that:
  • Provides quick and easy access to information about model objects, model files, and program settings
  • Permits quick plotting of objects (zones, structural elements, walls), histories, and charts
  • Permits quick listing of information in the Console
  • Provides quick access to related help topics
  • Permits streamlined watch information for selected parameters

• Export all (or only visible) 1D structural element (e.g., cables, rock bolts, beams, piles) data to tables and plot as charts or export to a CSV file
• Many updates of documentation, including links to YouTube videos
• Improvement on cut-plane where individual plot items can select a cut plane to sync to from a drop-down list
• Add geometry command to create geometry edges from txt or csv file.
  Add hide null gridpoint option
• Put zone joints to the results dialog
• Improved Rapid Tool to calculate Hoek-Brown material properties

Applies to FLAC3D and FLAC2D:

• CASM (Clay and Sand Model) constitutive model for assessing the static liquefaction potential of tailings dams from a relatively small set of material parameters, most of which can be calibrated from standard laboratory tests

Applies to FLAC3D:

• Plot Moment-Thrust and Shear-Thrust diagrams for structural elements

Applies to FLAC2D:

• Dynamic axisymmetric analysis
• Plot 2D contour isolines and include labels
• Plot grid points as labels or contoured in 2D
• Trigon (triangular) option added to the Voronoi Wizard
• Create lines in Sketch from an imported table of points
• Seven new examples and one updated example:
  • Axisymmetric Model of an Advancing Lined Shaft
  • Consolidation of an Embankment using Soft Soil
  • Consolidation of an Embankment using Mohr-Coulomb
  • Lined Tunnel in Saturated Ground
  • Saturation and Draining of a Caisson
  • Capillary Infiltration in a Dry Caisson
  • Deformation caused by filling of a Caisson
  • Updated dynamic analysis of a Tailings Dam to include CASM

• Fluid flow in 3DEC now works for meshes imported from Griddle

Applies to MassFlow:

• Massive simulation speedup in MassFlow when you have lots of draw points and lots of markers

Applied to PFC:

• Add bonded-particle modeling document.

New features and improvements added to 9.3:

• FLAC3D/FLAC2D:
  • Sketch: add an option to combine DFN
  • Extruder page accepts drops
  • Enable MPI creep with cluster option
