In this project we introduced and implemented the concept of virtual topology.
The virtual topology is an enhancement of the standard B-Rep for solids, in which the geometric and topological entity definitions, as defined in the standard B-Rep are uncoupled, thus allowing topological entities not corresponding to geometric ones.

The use of virtual topology for different CAD/CAM applications is studied with the focus on mesh generation.
This project is a combined research with Fluent Inc., a major developer of CFD (computational fluid dynamics) design and simulation software. The virtual topology was implemented as part of the GAMBIT CFD preprocessor, (Fluent Inc).
