Abstract

Computational simulations for complex geometries nowadays often deal with unstructured grids. That’s why scientific visualization must also be extended to these grid types. A visualization system is presented which works with any type of unstructured grids, i.e. arbitrary polygonal and polyhedral grids. Results from finite volume (cell-centered) and finite element methods can be visualized. Additionally time-dependent data can be processed and interpolation between time steps is possible. This data may be transfered directly from a simulation program and therefore on-line visualized. To integrate this task into a computational simulation an object-oriented interface is presented which allows an easy connection of simulation and visualization.
