Trajec3D Version 1.5.5 available for download
Updated: Dec 15, 2019
The changes to this version of Trajec3D are based around user requests, let me know if the additions works for your particular applications:
Request 1: Statistical functionality My impression is that the statistical analysis requirements are mostly basic, such as the number of fall bodies on particular elevations. This can be done manually, but is time consuming and not an elegant solution. I added a histogram chart as shown at the bottom of this post. The number of bins can be manually selected, and the highest and lowest elevations of the fall bodies are automatically used to determine the bin ranges. See the chart image for a visual explanation.
Request 2: Remove paths for deleted fall bodies Spurious bounces occasionally occur in rigid body analysis. These can easily be visually identified and should be discounted in any analysis. Problem is that removing their paths in the past with "Delete - Hide meshes of a single path" was temporary, and when refreshing the paths with the "Path" button just brought them back. If you now delete a fall body with "Delete - Delete a single fall body", all information for that fall body is erased. If you thus refresh the paths now, these path meshes will not return.
