Abstract
Systems and methods for creating a computerized model containing polydisperse spherical particles packed in an arbitrarily-shaped volume are disclosed. To create the computerized model, a plurality of polydisperse spherical particles having statistical properties according the characteristic profile (e.g., minimum and maximum sizes and size distribution) is generated. First portion of the particles is used for forming a border layer within the volume's boundary. Any hole in the border layer is sealed with one or more null-sized particles. Second portion of the particles is used for filling up an interior space in a layer-to-layer scheme from the border layer inwards. The layer-to-layer scheme includes searching a best suitable location from a list of size-ranked candidate locations using power diagrams. Each of the second portion of the particles is allowed to pass through holes in the current layer towards the border layer when possible.
