PFC 6.0 is now available.  This new version provides major enhancements for modeling capabilities, software interoperability, and updated graphics. Convex Rigid Blocks You can now model convex rigid polygons (2D) and polyhedra (3D). This allows modeling of non-spherical objects when the shape is of importance (granular or cohesive systems) without requiring clumps. Contact detection and resolution use a variation of the GJK (Gilbert–Johnson–Keerthi) algorithm with only one contact between two objects (i.e., no sub-contacts) to maximize efficiency. Interactions between rigid blocks and between other PFC components, such as balls, clumps, or walls, are possible using regular contact models. Similar to balls and clumps (PFC) and blocks (UDEC/3DEC), a fully dynamic solution scheme is employed. Convex rigid block utilities include: Easy shape creation … Continue reading Itasca PFC 6.00.10
