TYPE: Desktop, network, web, and node-locked licenses Any FLAC3D constitutive models suitable for plane-strainĪ FLAC2D license will permit two instances to run on the same computer.Simplified coupled fluid-flow mode (no saturation mode).New and faster implicit saturated-fluid/thermal solver.
Maxwell damping for faster dynamic modeling.More built-in FISH functions, including email functionsįLAC2D will also be released with new, Version 9 features, including:.Results files (limited data files smaller than Save files).Project bundles (collection of project files).
More sophisticated and powerful plotting. Discrete Fracture Network (DFN) generation and template features. Geometry import and use in model construction and plotting. Built‐in text editor with keyword highlighting, line numbering, search and replace, and more. Improved, interactive HELP with online documentation. Like FLAC3D, FLAC2D uses the Version 7 common framework and user interface (UI).Īs part of the common framework UI, FLAC2D includes many features not available in FLAC, such as:. FLAC2D commands and FISH syntax match closely to those in FLAC3D and, in many cases, they are exactly the same, absent the z-coordinate. Grids may be structured or unstructured, but in either, case zones and gridpoints are identified by IDs, spatial location (i.e., x,y-coordinates), or group names - rather than by i, j indexes - making it easier to learn and work with. In order to avoid confusion with FLAC 8.1, FLAC2D (and all upcoming Itasca software releases) will skip Version 8 and launch as Version 9.įLAC2D will be different from FLAC in several important ways: The Model Pane includes interactive boundary identification, group specification, property and constitutive model assignment, zone densification tools, and will include tools for interactive creation and property assignment to structural elements. The Sketch Pane includes drawing, DXF import, automatic meshing, and grouping tools. As with FLAC, models can be constructed and altered using commands and FISH, but also interactively within the Sketch Pane and the Model Pane. 
Similar to FLAC, FLAC2D adopts a finite-volume approach and uses plane‐strain formulation. Coming in 2022, we would like to introduce you to FLAC2D. This will also make the user experience more consistent between the different programs and improve future development. As a 2D version of FLAC3D, FLAC2D combines the efficiency of FLAC and the power of FLAC3D. FLAC2D represents a giant step forward for Itasca's foundational, two-dimensional numerical modeling software.
