Program Overview

✅ NEW: FLAC2D’s new, large-strain, automatic remeshing functionality for extreme displacement continuum modeling. This extends and improves upon FLAC 8.1’s rezoning logic, making remeshing easier to use for multiple constitutive models in the same simulation, dynamic models, and coupled models.

✅ NEW: Munson-Dawson creep constitutive model for simulating excavations in evaporites.

✅ IMPROVED: Automated factor-of-safety analysis is more flexible: exclude local shear-strength-reduction zones and run analyses including null or elastic regions.

✅ IMPROVED: In FLAC3D, the Sketch tool now extrudes 2D profiles along linear or curved paths with offsets and full domain generation—ideal for tunnel modeling.

✅ IMPROVED: The concrete constitutive model can now be assigned to structural support elements, such as beams, piles, shells, and liners. And circular shell elements can be easily added; couple these to piles and the concrete constitutive models to efficiently simulate thick concrete columns.

✅ NEW: Numerous new examples and verifications have been added for both FLAC2D and FLAC3D.

✅ NEW & IMPROVED: Strain-softening models, Python scripting update, Hoek-Brown Rapid Tool, and fluid flow in 3DEC.

💡 CUTTING EDGE: Also, as part of this v9.6 release, ITASCA is excited to announce the release of BETA versions of MPoint2D and MPoint3D, ITASCA newest software the utilizes a material-point-method (MPM) approach for extreme and immense deformation analysis. These products can be used on their own or coupled FLAC3D or FLAC2D. Ideal for modeling earth structures, tailings dams, and landslides. ITASCA is actively seeking BETA-testers to provide feedback on MPoint prior to being officially released.

🚀 Point releases are available to anyone with a Version 9 subscription, or maintenance, license of FLAC3D, FLAC2D, 3DEC, PFC3D, PFC2D, or MassFlow.
