This paper presents an integrated method for the simulation of mixed 1D / 3D system models in the domain of building energy supply systems. The feasibility of this approach is demonstrated by the use case of a solar thermal system: the sub-model of a hot water storage is modeled as a detailed threedimensional CFD model; but the rest of the system model (solar collector; hydraulics; heat exchanger; controller etc.) is modeled as a simplified component-based DAE model. For this purpose; the hot water storage model is simulated with ANSYS CFD. This detailed sub-model is embedded in the solar thermal system model; which consists of component models of the Modelica library FluidFlow and is simulated with Dymola. The numerical coupling and integration of both sub-models is realized by the use of the co-simulation environment TISC. With a comparison of a pure Modelica system model and a mixed 1D / 3D system model of the same solar thermal system; advantages and disadvantages of both simulation approaches are worked out.

Keywords: Co-simulation; Mixed 1D/3D modeling; energy building and plant simulation
