Existing techniques for animation of object fracture are based on an assumption that the object materials are homogeneous while most real world materials are heterogeneous. In this paper, we propose to use movable cellular automata (MCA) to simulate fracture phenomena on heterogeneous objects. The method is based on the discrete representation and inherits(More)
A key approach to visualizing a flow field is to emphasize regions with significant behavior. However, it is difficult to give concrete criteria for classifying feature regions. In this paper, we use a novel framework in which fuzzy sets are used to determine flow features: Fuzzy relationships assess structural properties of features. A fuzzy c-means-like(More)
In the field of computational fluid dynamics (CFD), the upwind finite volume method (FVM) is widely applied to solve 3D flows with discontinuity phenomena (e.g., shock waves). It produces unstructured data at the center of each cell (cell-centered data) with the flow disconti-nuity constraint on the inner-face between face-neighboring cells. For(More)
