The workshop will bring together a unique set of top researchers from geometry processing, computational geometry, geometric design, formulation of simulation models, real-time computation for interactive simulation, isogeometric and higher-order isoparametric design, and non-meshed approaches. The focus will be on presenting the state-of-the-art in a tutorial fashion to develop a more holistic approach to reverse the tendency towards specialization that risks neglecting feedback to the overarching set of challenges. Pointers and introductions to available tools, code or theory will be part of the presentations, e.g. opensource software packages such as sofa, blender, bullet, CGAL, etc.. and select propriertary tools from Autodesk and NVidia.

The interactive design and analysis cycle} and \emph{interactive surgical simulation, where model deformation and modification tightly link analysis and design will be concrete focal topics.

To shorten and improve the outcomes of the design-analysis cycle, the workshop will highlight integrating novel techniques that range from isogeometric design including irregularities, to new hierarchical spline spaces, to low-degree high-quality spline surfaces, co-rotational PDE models, collocation with extended B-splines, and convolution improvement of discontinuous Galerkin computations. The topics challenge the disparate groups to work together on the prediction of properties, adjustment of the geometric or physical model and possible printing of 3D prototypes. Interactive surgical simulation includes challenges in collision detection, collision response in the form of real-time force-feedback, soft-tissue simulation, cutting and tearing and visual appearance. Such challenges go far beyond the usually well-fenced application of numerical algorithms. Surgical simulation has obvious high societal impact by supplementing the training of surgeons and preparing patient-specific interventions. Through engaging on the specific topics, and exchange of major recent advances in technique and technology, we expect to foster new interaction between these different communities.
