Abstract: An adaptive material point method for simulating and rendering of solid materials is disclosed. During each time step, a simulation application splits and/or merges particles according to a resolution of a grid and assigns properties to the split/merged particles. The simulation application then rasterizes particle information, including masses and velocities, to the grid, on which forces and/or collisions are computed to obtain updated velocities. Grid information, including the updated velocities, is then transferred back to the particles. The transfer from particles to grid and back from grid to particles may employ different transfer functions. In particular, a quadratic transfer function may be used to transfer information from the particles to the grid, while a linear transfer function may be used elsewhere, including to transfer information back from the grid to the particles.

Abstract: Physical tools for trimming operations in forming of a sheet-metal part are set up based on numerically-simulated structural behaviors. FEA model representing a stamped sheet metal before trimming and a trimming operation setup are received. Each trim-steel contains a set of cutting-edge nodes associated with trim vector. At least one trim line is established by projecting cutting-edge nodes onto the FEA model according to the trim vector. Numerically-constrained node-pairs along the trim line are created at intersections with edges of crossed finite elements. FEA model is modified by splitting the crossed finite elements to preserve original geometry and to ensure numerical stability. New finite elements are defined using one of the nodes in corresponding node-pairs such that no finite element straddles the trim line. At each solution cycle of a time-marching simulation of trimming operations, simulated structural behaviors are obtained as the scrap portion(s) deforms and falls accordingly.

The method also comprises upon a modification of the data defining the 3D modeled object, determining a strong graph, wherein the strong graph is the graph of strong components of the modeling graph, and updating the 3D modeled object according to a traversal of the strong graph.

Abstract: A highly scalable cluster of computing nodes simulates large numbers of objects interacting in a space defined by an octree of cubical elements. Each cube of the octree is enclosed within a corresponding padding sphere. Interacting objects are quickly identified by determining which of the padding spheres are candidate spheres that satisfy an interaction criterion, considering candidate objects located in the cubes that correspond to the candidate spheres, and determining which of the candidate objects meet the interaction criterion. The computing workload can be efficiently parallelized among nodes of the cluster by assigning the objects to the nodes in approximately equal numbers, each node being responsible for managing the objects assigned thereto. Inter-node data traffic can be minimized by reassigning frequently interacting objects to the same node. The cluster can be scaled simply by adding more nodes to the cluster, and redistributing the objects equally among the nodes.

Abstract: A method for designing a 3D modeled object can implement a modeling graph having nodes that represent geometrical objects and arcs that each represent a relationship, wherein procedural relationships are represented by unidirectional arcs, wherein the relationships linking the geometrical objects further include live relationships that are represented by bidirectional arcs, and wherein the provided modeling graph respects a criterion that all the arcs of each strong component of the modeling graph are bidirectional. Upon adding a relationship linking two of the geometrical objects that are included in the data defining the 3D modeled object before the addition, the method selects two geometrical objects to be linked by the relationship to be added, the selection being performed according to the criterion.
