Fundamental Domains for Integer Programs with Symmetries
We define a fundamental domain for a linear programming relaxation of a combinatorial integer program which is symmetric under a group action. We then describe a straightforward w...

Ultrascalable Implicit Finite Element Analyses in Solid Mechanics with over a Half a Billion Degrees of Freedom
The solution of elliptic diffusion operators is the computational bottleneck in many simulations in a wide range of engineering and scientific disciplines. We present a truly sca...

Boundary treatment for virtual leaf surfaces
When working on fitting leaf surfaces for use with virtual plant models [Room et al. 1996] we encountered the unsatisfactory situation of receiving a smooth surface model that is...

Adaptive Simulation of Soft Bodies in Real-Time
This paper presents an adaptive technique to animate deformable bodies in real-time. In contrast to most previous work, we introduce a multi-resolution model that locally refines...

Block placement with symmetry constraints based on the O-tree non-slicing representation
The ordered tree (O-tree) representation has recently gained much interest in layout design automation. Different from previous topological representations of non-slicing floorpl...
