An Algorithm for Tensor Product Approximation of Three-Dimensional Material Data for Implicit Dynamics Simulations [chapter]

Krzysztof Podsiadło, Marcin Łoś, Leszek Siwik, Maciej Woźniak
2018 Lecture Notes in Computer Science  
In the paper, a heuristic algorithm for tensor product approximation with B-spline basis functions of three-dimensional material data is presented.  ...  The algorithm has an application as a preconditioner for implicit dynamics simulations of a non-linear flow in heterogeneous media using alternating directions method.  ...  Our intuition is that 100 iterations (100 components of the tensor product approximation) should give a well approximation, and thus we can use the implicit method not bounded by the CFL condition, which  ...

Real-Time Simulation of Deformation and Fracture of Stiff Materials [chapter]

Matthias Müller, Leonard McMillan, Julie Dorsey, Robert Jagnow
2001 Eurographics  
Existing techniques for real-time simulation of object deformation are well suited for animating soft materials like human tissue or two-dimensional systems such as cloth.  ...  We present a stable hybrid method for simulating deformation and fracture of materials in real-time. In our system, the effects of impact forces are computed only at discrete collision events.  ...  This dynamic characteristic of the data limits possibilities for precomputing efficient data structures. It also creates a potential for intra-object collisions.  ...
