HARPACEAS FLAC и FLAC3D

Computational • Large-strain simulation of continua, with optional interfaces that simulate distinct planes along which slip and/or separation can occur • Explicit solution scheme, giving stable solutions to unstable physical processes • Groundwater flow, with full coupling to mechanical calculation (including negative pore pressure, unsaturated flow, and phreatic surface calculation) • Convenient specification of general boundary conditions • Structural elements (including non-linear material behavior), with general coupling to the continuum • Library of material models (e.‎g.‎, elastic, Mohr-Coulomb plasticity, ubiquitous joint, double-yield, strain-softening, modified Cam-Clay, and Hoek-Brown) • Pre-defined database of material properties; users may add and save their own material properties specifications to the database • A range of optional modules, including: thermal and creep calculations, dynamic analysis capability, two-phase fluid flow model, and user-defined constitutive models written in C++ • Coupling to infinite elastic boundary • Statistical distribution of any property with extensive facility for generating plots of virtually any problem variable • Built-in language (FISH) to add user-defined features (e.‎g.‎, new constitutive models, new variables or new commands) Environment • Full graphical interface with built-in access to command-line • Several grid generators for common shapes • Project-tree simplifies project tracking, management, revision, and parameterization • Continuous update of selected plots while FLAC is executing • Graphical output in a wide range of industry-standard formats with cut-and-paste facility • Built-in MOVIE command and accompanying viewer utility to animate model results • Customizable program environment that may be saved to reflect the user’s preferences • Rapid movement from the modeling environment to the code output using a multi-pane program layout • Built-in slope modeling module (FLAC/Slope) for rapid factor-of-safety analysis of slopes • HTML-based Help accessed from the Help menu describes use of the user-interface; and provides access to the full FLAC Manual.‎
