    33The Boussinesq approximation requires incompressibility of the flow, but the integration of the governing equations formulated in Sect. [wiki:doc/tec/gov governing equations] does not provide this feature. Divergence of the flow field is thus inherently produced. Hence, a predictor corrector method is used where an equation is solved for the modified perturbation pressure after every time step ([#patrinos1977 e.g., Patrinos and Kistler, 1977]). In a first step, the pressure term
