Towards integrated object-oriented Computational Fluid Dynamics environments: Interactive Domain Editor

The simulation of fluid flows around complex geometries starts to be computationally possible. Thus, it has become important to provide the Computational Fluid Dynamics (CFD) community with tools that allow easy manipulation of physical geometry and, for an efficient use of resources, interactive splitting of computational domain. We propose here an object-oriented approach to the definition of an Interactive Domain Editor (IDE). We show how this can be a kernel of an integrated environment for CFD. We finally describe the first results of a test implementation of IDE. 1 Introduction In recent years, due to the increasing power of computers, it has become feasible to simulate fluid flows in complex geometries [Kar89, Ors80]. This has introduced a new level of complexity in the field of Computational FluidDynamics (CFD): users need to be able to describe much more complex computational spaces to flow solvers; for an efficient use of computational resources the computational domains hav..
