No. I just thought about users, that already use discretization option to get mass of clumps (like me ...) If the users now use the same script with new yade version, it will give different results (maybe unnoticed by the user). >As far as inertia matters, there is no point in subdiscretizing this tiny >sphere which is 1000 times smaller that the clump. >But if you really want to do it you can: discretization=10000. Yes I see the problem and I agree with the change in code, but please give a note for the users! Now to the doc ... After a closer look I think there should be no change in [1] since it just says that aabb is discretized (but not how). There should be an update of [2] instead. Also it needs an update of the examples/clumps section ... >p.s. Please don't cc me or anybody else when sending email to bug/aswers/lists because it generates duplicates I did not cc anyone. This seems to be a bug in launchpad mail delivery system. I get double-posts nearly every day. [1] see above [2] https://yade-dem.org/doc/yade.wrapper.html?highlight=clump#yade.wrapper.BodyContainer.clump -- You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. https://bugs.launchpad.net/bugs/1474956 Title: Clump::updateProperties discretization not defined robustly Status in Yade: Confirmed Bug description: Most likely the reason for performance drop reported in [1] dx in the voxel decomposition is minRad/discretization. The problem is when a sphere of radius 1 is member of a clump which aabb has the size 1000 (for instance). Using the minimal discretization=1 gives a number of voxel = 1e9 in such case and it is no possible to go below this number. I think discretization should refer to aabb size, not member size. I have this fixed locally, let me know if you agree with the fix.
