Lumped Mass Method

• Models each rock as a particle with only mass
• Models impacts using both normal and tangential coefficients of restitution
• Models pseudo-rotation
• Models sliding using friction angle

Rigid Body Method

• Define rock shape, size, and mass:
  • Polygonal rock shapes and smooth shapes
  • Custom Polygon rock shapes
• Models sliding and rolling with dynamic coefficients of friction and rolling friction
• Variable friction with sliding distance
• Viscoplastic ground drag
• Forest damping for vegetated slopes
• Variable slope roughness

Seeders

• Specify rock source locations using point seeders, point seeder series, and line seeders
• Unlimited number of rock source locations
• Probability settings for seeder starting velocities and rotations
• Pseudo-random number generation

Slope

• No restrictions on slope geometry (e.g., overhanging sections)
• Statistically defined material properties
• Model crest loss
• Statistically defined slope vertices
• Import/export material properties
• Import .dxf, .crsp (version 3 & 4) files
• Define slope based on segment lengths and angles

Enhanced Barrier Analysis

• Unlimited number of barriers
• Single variable barrier sensitivity analysis
• Double variable barrier sensitivity analysis
• Reusable barrier properties
• Built-in library includes Maccaferri, Trumer-Schutzbauten, Geobrugg, PFEIFER Protective Structures and RISP barriers

Graphs Produced

• Histogram of rock endpoint locations
• Plot max, mean, and/or percentile graphs (energy, velocity, bounce height, etc.) along slope
• Distribution graphs show the distribution of bounce heights, energies, etc. at specific locations (same data as envelope graphs)
• Create histograms or cumulative distributions for specific locations (impact locations, energy, etc.)
• Toggle end reasons, seeders, rock types, and rock shapes added to Endpoint location, envelope, and distribution graphs
• Group plots of runout distances and barrier impacts for slope sections batch exported from RocFall3
