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.

New in Sketch

Applies to FLAC2D

• Improvements the joint-set wizard
• Added a wizard to generate DFNs (discrete fracture networks)
• Added a wizard to generate Voronoi- or tetrahedral-shaped BBM (bonded block models) based on zone-joints
• Can now create points and edges from table in Sketch

Contact Models

Applies to 3DEC

• Velocity weakening
  • The Velocity Weakening joint model is similar to a slip-softening model, except that the friction reduces as a function of increasing velocity rather than slip distance.

Structural Elements

Applies to FLAC3D and 3DEC

• Rapid Tool for Cable Bolt Properties from Pullout Calibration
• New bar chart for 1D structural elements

New Examples

Applies to FLAC2D

1. Factor of Safety Calculated for Various Jointed Rock Slopes
2. Rainfall on a Slope
3. Tunnel Through a Rock (Voronoi)
4. Tailing Dam Static Liquefaction
5. Dewatered Construction of a Braced Excavation
6. Uniaxial Compression Strength (UCS) Test on a Fractured Sample

Applies to FLAC3D

1. Assessment of Fault Slip Potential from Sill Pillar Mining

And more ...

Applies to FLAC2D

• Can now generate topography (zones) from a table of x, y coordinates

Applies to 3DEC

• Added a structure hybrid import command to create hybrid bolt elements from an outside source (e.g., DXF, STL, ITASCA geometry)
• Added a progress bar for joint plotting
