Isogeometric Analysis

One of the major problems in product design is the gap between CAD, where the geometrical shape of the object is defined, and CAE, where the mechanical behavior of the shape is analysed. The gap results from different representations used for design (based on NURBS) and analysis (based on a finite: The design, encapsulated in a CAD model, is approximated by a finite element mesh (FEM) for analysis. Isogeometric Analysis refers to the extension of the standard FEM to representations used in CAGD. By working directly with the CAD model, isogeometric analysis effectively eliminates the problems associated with generating a finite element mesh from a CAD model.

Virtual Reality

Virtual Reality is the simulation of artificial environments for the purpose of life like, very realistic experiences. The goal is to immerse the user and stimulate all senses. Obviously the sight is our main target. This can be experienced, for example, in the DAVE, our definitely affordable virtual environment. The DAVE is a cubicle with 3.30 m wide walls consisting of four active stereo screens and head tracking. Being totally immersed also requires to interact with the virtual world in unusual and innovative ways. Applications for Virutal Reality are for example: - Visualisation of not yet existant places and objects - Learning in dangerous situations - or with expensive equipment - Evaluation of tasks in a controlled environment.
