Some aspects of Virtual Reality based computational steering of indoor air flow computation

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.     «
