Hi, I agree, that in some special cases aabb should be used for discretization, but...
... it should be downward compatible (user can decide if he/she want the discretization this way or this way ... so a new bool is needed in Clump::updateProperties: discretionAabb = false [default]) ... it needs a lot of extra code modification (each function, that calls updateProperties directly or indirectly) ... it needs an update of clump section in the DEM background manual [1] Regards, Christian [1] https://yade-dem.org/doc/formulation.html#clumps-rigid-aggregates -- 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.
