Trajec3D Version 1.5.3 now available for download

Updated: Dec 15, 2019

The new additions open the potential to even more realistic rock fall simulations, and Trajec3D can now accommodate different coordinate systems correctly.

  • The loading of custom shapes as DXF-files was previously unstable and limited to triangulations with 500 vertices. This functionality is now stable and allow fall body triangulations of up to 65 000 vertices.

  • The coordinate system typically used on sites in Australia is in the order "Easting", "Northing" and "mRL". As some users have to accommodate other coordinate systems as well, the coordinate system can now be selected with the pop-up form show below:

Loading custom fall body shapes has much potential to back-analyse specific rock fall incidents. A rough fall body shape can be generated from the rock that fell, or a triangulation mesh could be generated with the on-site photogrammetry software. I will further investigate the potential to use the free photogrammetry software Autodesk 123 Catch to generate fall body shapes for Trajec3D.
