3D Assessment of Slopes at Risk for Rockfalls

3D Model Creation

Constructing rockfall models is easier and faster than ever. Import ground surfaces from geological modelling or mine planning software or with the Terrain Generator, import digital elevation models directly from satellite data coordinates to speed up the model creation process. Using RocFall3’s other built-in surface construction methods, you can also build surfaces from point cloud data, elevation data, polyline lofting, or by extrusion.

Integration with RocFall2

The integration of RocFall3 with its 2D counterpart RocFall2 allows you to import models directly from RocFall2 and extrude the geometry to easily create a 3D model. You can also define 2D sections within a full 3D model and batch export them back to RocFall2 with predefined materials and parameters to seamlessly run group analyses in 2D.

3D Barrier Design & Analysis

Analysis of rockfall stabilization measures is crucial to any slope design. RocFall3’s barrier logic is designed after Rocfall2 which provides flexibility in having an unlimited number of barriers, deformable barriers, energy capacity, elongation, adjustable heights, and more.

RocFall3 across Applications

Account for loss of bench width, assess the risk of runoff reaching lower operating levels, and design mitigation measures for your mines.


Analyze instabilities in highly jointed rock slopes which pose risks for kinematic slope failures.

Assess the risk of rockfalls reaching roadways and design and model remedial measures such as barriers and berms.

Explore the latest features in RocFall2

The rigid body analysis method now accommodates 16 rock shapes. Define rock seeder properties using the new rock shape library.


Like RocFall2, RocFall3 supports both the lump mass and rigid body analysis methods. The lump mass engine includes impacts and sliding physics. The rigid body engine accommodates various rock shapes and multi-contact physics to calculate impacts, sliding, and rolling.

RocFall3 allows you to easily view rock paths, trajectories, and final stopping locations. It can also contour various data, such as the energy and bounce heights along the path, while plotting the runout distribution and spatial distribution of stopping locations. RocFall3’s suite of visualization tools includes runout distributions, barrier statistics, and its user-friendly interface makes it easy to filter your data.
