In addition to the Droplet Histogram Tool I was asked for a routine that calculates the penetration depth and the injection cone angle of droplets. The attached tool does these two things. When launched a small GUI pops up which asks the user for the measured particle data, the time step for calculation and the percentage of droplets within the calculated cone angle. The default value here is 80%. With this value the routine tends to stop at a cone angle which comes close to the groplet injection geometry.
This routine is written as a user defined tool. If you have an existing directory for your own tools just put it together with the image into that directory. Otherwise it can be used as a standalone tool as well if line 360 is activated. Please contact me if you have any problems (firstname.lastname@example.org).
