Abstract: Abstract This report briefly summarizes the current state of the HLRB II project h005y which focuses on the interactive simulation and local assessment of indoor thermal comfort. The research group therefore develops a Computational Steering Environment (CSE) which consists of a parallel CFD kernel, a fast 3D mesh generator and a virtual reality-based visualization and steering component. The numerical method is based on a lattice Boltzmann algorithm with extensions for simulations of turbulent convective flows. Utilizing high-performance supercomputing facilities, the CSE allows for modifying both the geometric model and the boundary conditions during runtime coupled with the immediate update of results. This is made possible by a space-tree based partitioning algorithm that facilitates the meshing of arbitrarily shaped, complex facet models in a matter of just a few seconds computing time. Ongoing developments address the integration of a radiation solver, a human thermoregulation model and a local thermal comfort model.
