+Buildings are primarily realized as obstacles that react to the flow dynamics via form drag and friction forces by assuming a constant flux layer between the building surface and the adjacent air volume. A simple thermodynamic coupling is also possible by prescribing surface fluxes of sensible (and latent heat) at any of the building surface grid elements. Thermodynamic interactive buildings are realized within the [wiki:doc/palm4u PALM-4U] components.
 
 The technical realization of the topography and treatment of surface-bounded grid cells is be outlined in Section [wiki:doc/tec/topography topography implementation].
