Question #706774 on Yade changed: https://answers.launchpad.net/yade/+question/706774
Status: Open => Answered Jan Stránský proposed the following answer: > what I need is the calculation of the gradation curve in general In general it is same as you would do it experimentally. For a set of defined "passing" sizes, you count particles smaller than that size. See implementation of psd function [2] > And I don't know how to calculate the size of a clump. More specially, I don't know which length can represent the size of the clump and be used for gradation calculation. The length of the longest axis? Depends on your definition. Calculation then should not be too difficult. Longest axis is one choice. For real sieve analysis, probably the longest size is not the most important, as it would pass "perpendicularly" to the longest axis? So maybe the second longest principal axes? Or longest dimension perpendicular to the longest axis? I don't know.. There are more options. > I have shared some STL files for your reference Please see [1], section "Please, no external links!". An artificial simple example should be enough.
