EDEM size distribution

The size distribution is set for the particle shapes in each Bulk Material. The scaling options for the size distributions are all relative to the defined particle size. If the 'scale by Radius' option is used, all length dimensions will be scaled in direct proportion to the value specified. If 'Scale by Volume' is specified all length dimensions will be scaled to the cube-root of the
