Embracing Innovation with RocFall3 – Features, Application, and Integration

A 3D statistical analysis program, RocFall3 is designed to assess slopes at risk for rockfalls. The program can determine Energy, Velocity, and Bounce Heights along multiple rock paths. Not only can it spatially visualize runout distance on the 3D slope geometry but also generate distribution graphs and automatically calculate comprehensive statistics. Additionally, RocFall3 allows you to perform both Lumped Mass and Rigid Body rockfall analyses.

3D Model Creation

Constructing rockfall models is easier and faster than ever. Import ground surfaces from geological modelling or mine planning software along with digital elevation models from various sources in industry-supported file formats (obj, dxf, stl, dtm, etc.).

The Terrain Generator allows you to import digital elevation models from satellite data. Using RocFall3’s built-in surface construction methods, you can build surfaces from point cloud data, elevation data, polyline lofting, or by extrusion.

Analysis Methods

Like RocFall2, RocFall3 consists of both lumped mass and rigid body analysis methods. The lumped mass model includes impact and sliding physics, whereas the rigid body engine has a sphere impact model. Both lumped mass and rigid body physics engines can scale the coefficient of restitution (Rn) by velocity and mass.

Material Region Editor

The material region editor lets you select regions on the slope surface and apply material properties quickly and easily. You can select the area based on elevation, user-defined polygonal regions, or the various built-in triangle selection facilities available in the Rocscience suite of programs. When importing RocFall2 models, your material regions are created automatically.

Analysis of rockfall stabilization measures is crucial to any slope design. RocFall3’s barrier logic is designed after RocFall2 which includes an unlimited number of barriers, deformable barriers, energy capacity, elongation, and adjustable height.

Rockfall Data Visualization

The ability to easily visualize and interpret analysis data is crucial for any rockfall model. RocFall3 allows you to view rock paths, trajectory, and final stopping location. It can also contour various data like energy and bounce height along the path while plotting runout distributions and spatial distribution of stopping location. RocFall3’s suite of visualization tools includes runout distributions, barrier statistics, and easy filtering of data for your analysis.

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 a 2D section within a full 3D model and export it back to RocFall2 with predefined materials and parameters to seamlessly run 2D analysis.

How does RocFall2 -RocFall3 integration streamline your 3D rockfall modeling & analyses?

In the past, engineers wanting to conduct both 2D & 3D analyses would have to spend time creating these models separately. Now with RocFall3, this is no longer the case as it can analyze a RocFall2 model and allow you to extrude it. Simultaneously, properties of the RocFall2 model can also be imported into the 3D model, reducing incorrect movement of properties between 2D & 3D programs.

Like our other 3D programs, Slide3 and RS3, you can now create multiple 2D sections within RocFall3 model. These sections can then be imported into RocFall2 with all the properties transferred, reducing time spent modelling and potential errors while moving models between 2D and 3D analyses.

Step-by-step process of importing RocFall2 files into RocFall3

  1. Choose the import option Import RocFall2 File
  2. Enter the extrusion length and how you want to convert the seeders.
  3. Click OK and the properties and settings are automatically imported into the RocFall3 model.
  4. Press compute and you can immediately see the 3D simulation of the 2D model.

Seamless steps to import RocFall3 files into RocFall2

  1. Export 2D sections to Rocfall2 from Rocfall3 using the Section Creator tool to create a 2D section through the 3D model.
  2. Either interactively place the section through the 3D model or use exact locations by typing in a point on the section and the strike of the section.
  3. Then, simply select export this section. If you have RocFall2 installed on your computer, the model with all associated material assignments and properties will be opened automatically.
  4. Simply click the results button to see the 2D equivalent analysis.
