Abstract: This study examines natural convection from a hot cubical structure buried inside a fluid saturated porous media under suction/injection induced forced flow conditions. The numerical computations are carried out by a segregated finite element approach under the paradigm of domain decomposition technique. Suitable sparse data structures and algorithms are designed for efficient implementation on a cluster of PCs called ANUCLUSTER under ANULIB parallel processing environment. The parallel numerical simulations are carried out for various values of Ra and for different sizes of isothermal hot cubical objects. Results have been presented in the form of Nusselt number, temperature and velocity vector plots.
