This thesis presents a software concept for CFD simulations, which follows the principle of 'Computational Steering'. According to this, an on-the-fly visualization of current computation results and, especially, the possibility of steering the simulation through user interactions during its execution are the key requirements. The interaction options comprise the adjustment of global flow parameters, the definition of boundary conditions and, in particular, the arbitrary modification of the geometrical layout of the simulated scene.
The computational kernel, which is performed on a supercomputer, is based on the Lattice-Boltzmann method. Concurrently, the visualization and steering front-end is run within a Virtual Reality environment. To demonstrate the applicability of the developed tool to support the engineer's design for an indoor ventilation system, it is used exemplarily for the interactive simulation of a real operating room.
