Solver for the Navier Stokes equations for the infinite Prandtl case in the Boussinesq approximation.

General non dimensional problem:

The model is developed on the OpenFOAM platform, based on pimpleFoam and buoyantBoussinesqPimpleFoam (See www.openfoam.org.) by Matteo Cerminara (https://github.com/cerminara) and Sara Lenzi.

The buoyancy term is written explicitly, no subgrid model is adopted.

Model equations of this code (OpenFOAM):

where n indicates the n-th PIMPLE iteration and m the m-th PISO iteration.

A tutorial folder is provided, to simulate a simplified (isoviscous, 3D) convection problem at infinite Prandtl number .

BCs: fixed temperature and free slip velocity on top and bottom, periodicity along horizontal directions.
