New features and enhancements are included in the latest releases of RS3 and Slide3 from Rocscience

Both RS3 and Slide3 feature improvements to geometry operations such as a new Simplify Geometry Triangulation feature, new Surface Triangulation tools, new Geometry Repair tools and more. Also new in both programmes is import of IDS Georadar live radar monitoring for contouring on the existing model. In RS3, there is a new Add Joint Surface feature and improved Contour Plane and Section tools. Finally, Slide3 now features support for probabilistic analysis, export of safety maps, the addition of Maccaferri and Tensar common support types, and much more.

Geometry improvements in RS3 and Slide3

New in both RS3 and Slide3 is a Simplify Geometry Triangulation option that allows users to simplify the triangulation of selected imported geometry to reduce the number of triangles. The Import Geometry process in RS3 and Slide3 has been enhanced with the incorporation of the validation and cleaning operations into a single post-processing step as the last step in the process. Together with the addition of Geometry Simplification, this enhancement makes the tool even easier to use.

In addition, to Simplify Triangulation, several other surface tools have been added to the Surface Triangulation tools array in RS3 and Slide3. These include:

  • Convex Hull creates a surface that envelops the selected geometries, i.e., a bubble that encloses all selected surfaces/lines/points. This can be used to recreate simplified slopes or ore bodies that were stored as unstructured triangle slopes.
  • Add Surface from Points creates a terrain-like surface from the vertices in imported or selected geometries (other surfaces, lines, and points). This is a common feature in 3D CAD tools that have 3D scans stored as point clouds for surface reconstruction.
  • Add Surface from Existing Contours creates a terrain-like surface from a set of lines. This is a common feature in 3D CAD tools that have 3D scans stored as elevation contours for surface reconstruction.

Two new tools have been added to the Geometry Repair tools in both RS3 and Slide3 to assist users do overall cleaning of the model.

Collapse Material Boundaries is a convenience function that gives users the ability to "union" adjacent solids that have the same material assignment over all stages in a project. From experience, unnecessary splits can occur to a unified solid that breaks up into small pieces. This increases the complexity of the model and reduces the speed of simulation. In previous versions, users could already clean up the model by manually selecting the pieces one by one and "unioning" them, but this can be tedious. Users can now simply use this function to have the program quickly merge all touching solids that have the same material assignments over all stages.

Discard Isolated External Pieces makes suggestions and removes floating solid pieces that are disconnected from the rest of the model.

New in both RS3 and Slide3 is the ability to export selected contour surfaces to a file, it will be useful to users who want to import contour surface information into other 3D geometry or data programmes for further analysis.

New import of IDS live radar data to RS3 and Slide3

Newly added to both RS3 and Slide3 is the ability to import live IDS radar monitoring data for contouring on the existing model. In previous versions of the program, users could import radar data from a CSV file. The difference now is that users can establish a direct live connection to a data server using a REST API. This addition of support for live radar data means Rocscience is one step closer to so-called intelligent slope design.

New and improved in RS3

A new Add Joint Surface feature in RS3 gives users the ability to select any set of surfaces and define them as joint surfaces.

Improvements to the Contour Plane and Section tools in RS3 now allow users to select plane entities before starting RS2 Section Creation or Contour Geometry operations. This streamlines these operations since, in previous versions, users had to manually specify the location of the plane before beginning the process.

New probabilistic analysis in Slide3

A major new feature in Slide3 is the ability to perform a probabilistic slope stability analysis to determine the effect of uncertainty or variability of input parameters on the results of the slope stability analysis.

For most real-world slope stability problems, the values of many input parameters are not very well known, therefore a probabilistic approach to the analysis of slope stability can be useful. In a probabilistic slope stability analysis, the user may assign statistical distributions to material properties.

By assigning a statistical distribution to one or more model input parameters, the user can account for the degree of uncertainty in the value of the parameters. Input data samples are randomly generated based on the user-defined statistical distributions. A given slip surface may then have many different factor of safety values calculated. This results in a distribution of factors of safety from which a probability of failure for the slope can be calculated.

Other features and enhancements in Slide3

Other new features in and enhancements in Slide 3 include:

  • Ability to export safety maps to a file with the factor of safety data
  • Addition of Tensar and Maccaferri geotextiles to the common support types library
  • Ability to get a summary of error codes with descriptions
  • Three new tutorials: Borehole Manager, Seepage Analysis, and Probabilistic Analysis
  • Improvements to the info viewer
  • General user interface improvements
