A critical review of domain decomposition techniques shows that there exist only few methods for incompressible flows. In the first part, we present such methods for linearised models, like the Stokes and the Oseen problems. Then we describe in more detail a non-overlapping method with interface conditions of the Robin type. Finally, we show a typical application of the latter method to a complex model appearing in indoor air flow simulation.
