This paper describes the content and the use of the new FluidDynamics Library which can be applied to carry out CFD simulations using Modelica as an open modelling language. Typical applications until now have been in automotive, aircraft and buildings development. In this paper a fire dynamics and smoke removal simulation is presented. These simulations are very important in the process of approving a building permission. The Fluid- Dynamics Library helps to identify promising ventilation and control setups and speeds up the simulation process significantly.
