Software Products

General

• Now freeware provided at no cost and with no time or size restrictions
• No CPU limits
• Simplified user interface and workflow
• Specifically designed to perform multiple analyses and parametric studies for slope stability projects
• Failure mode develops naturally – no need to specify a slip surface or failure mechanism
• Predict multiple, interacting failure mechanisms (failures can propagate)
• Structural interaction (e.g., rock bolt, soil nail, or geogrid) is modeled realistically as fully coupled deforming elements, not simply as LEM equivalent forces
• Extensive solution controls and options
• Multi-threaded mechanical calculations
• Built-in PDF manual and example files

Grid and Geometry

• Wizards for generating slope, bench, dam, and general surface grids
• Automatic and customizable meshing tools

Materials and Models

• Mohr-Coulomb, Hoek-Brown, and Ubiquitous joint materials are available
• Built-in materials library includes gravel, sand, silt, clay, and rock properties
• Add, save, edit, and import/export your own material properties with the library
• Easily define geotechnical layers

Boundaries and Conditions

• Automatic boundary conditions
• Apply stresses (Sxx, Sxy, Syy, normal, shear, and pressure) and forces (Fx, Fy)
• Cable structural support elements can be added as geosynthetic sheets or spaced (out-of-plane) ground reinforcement to simulate ground-structure interaction.
• Easily add a water table to include pore pressures for effective stress calculations
• Add a Mohr-Coulomb interface to represent a weak plane for faults, joints, or artificial boundaries
• User-defined gravity settings

Solutions

• Plane strain or axisymmetric analysis
• Automatic FoS calculations using the shear strength reduction (SSR) method
• Structural support elements, materials, and interface properties can be included or excluded as part of the FoS calculation
• Exclude model regions from the FoS calculation to capture the global failure
• Pseudostatic analysis with constant horizontal and/or vertical accelerations to represent an earthquake
• FLAC/Slope model records can be saved and imported into FLAC for additional analysis

Post-Processing

• Available plot items:
  • Materials
  • Shear strain rate contouring (failure surface location)
  • Velocity vectors (failure mode)
  • Pore pressure contouring
  • Model boundary or mesh
  • Water table
  • Applied conditions
  • Plasticity indicators (yielding/failure)
  • Ubiquitous joint angles
  • Ground reinforcement elements and axial forces
  • Calculated FoS (in legend)
• Export model plots as bitmap, postscript, and DXF formats
• Generate an HTML report with material, interface, and structural element property tables and solution table
• Optionally show resources to:
  • View all of the background FLAC commands generated as you create and run models
  • Query the model using FLAC commands
• Compare runs using different parameters, and even compare results from different projects
