I used a diamater number distribution provided by the manufacturer to calculate the Rosin Rammler-mean diamater and spread. As my results do not match my expectations I want to double check the diameter distributions injected.<\/p>\n<p><\/p>\n<p>First, I plotted a Histogram using data from trajectory samle files of two surfaces. These histograms indicate a rectangular distribution with 18 of the 20 bins around the same number of particles and the smalles diameters slightly less.<\/p>\n<p><\/p>\n<p>Then I calculated the number distribution using the initial values of the injection obtained by \/\/define\/injections\/lp\/myInjection. <br \/>Here the number distribution is extreme to the small diameters, with 1.3e+6 entries for the smallest diameter, 1.3e+3&nbsp; for the second smallest and then exponentially decreasing to 3. The volume distribution has a gaussian shape but should be skewed towards the larger diameters. <\/p>\n<p><\/p>\n<p>As I disabled breakup and all particles pass the surface of the histogram both plots shall indicate generally the same shape, but they do not.
