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
