Direct manipulation of flow geometries and boundary conditions in the course of transient CFD simulation in combination with real time updates of the results in a Virtual Reality environment allows a very flexible analysis of complex flow phenomena. This paper identifies the most challenging problems of this computational steering application and describes a solution approach based on a Lattice-Boltzmann (LB) CFD kernel. Our final goal is an interactive steering of turbulent indoor flow computations utilizing parallel vector computers. A prototype application demonstrating the feasibility of the concept is briefly presented.     «
