Improving algorithms and interfaces for interactive physical simulation serves to train the workforce, to create engaging movies and games, and to include humans in complex decision and optimization processes. Realistic, robust, and trustworthy simulation depends on the subtle interaction of geometric models and physical models, governed by partial differential equations and leveraging tools that range from geometry processing, computational geometry, geometric design, splines in meshing-less and iso-geometry approaches – all the way to real-time computation and interactive force-feedback.

The goal of this Dagstuhl Seminar is to present and contrast this rich set of techniques, and to foster new interaction between academia, industrial and government- sponsored labs in computer science, applied mathematics and engineering in order to chart future directions and formulate new research questions. Challenges to be addressed include: understanding and formulating mathematical models that bridge the divide between geometric modeling and engineering analysis; contrasting differing error categories in different sub-fields and their estimation; developing techniques that enable a faster design-analysis feedback cycle for interactive modeling and virtual prototypes, and that cope with inexact external forces, UI and feedback and interactivity; extending fast model reduction techniques to non-linear models (e.g. of elasticity) and enabling fast updates after substantial state changes; improving the interface between geometry modeling and physics simulation libraries such as Blender, SOFA, bullet, CGAL, and G+smo.
