1.2.0 Abbreviations, notation and units,bounds. The mathematical background of FEM is functional analysis. The FEM was introduced into the field of computational fluid dynamics (CFD) by Chung (1978), Baker (1983), Huyakorn & Pinder (1983), Diersch (1985) and others. The FEM is a more general approximation technique containing many finite difference schemes as special cases (Chapter 6).

Porous Mediaich occupy the void space (Fig. 3.1). Fluids are immiscible, if a sharp interface is maintained between them. In general, a phase is defined as a part of a continuum, which is characterized by distinct material properties and by a well-defined set of thermodynamic state variables. State variables de

Finite Element Methoderminus -. — was introduced by Turner et al. (1956). The concept of the finite element technique consists in a subdivision of a complex structure into small substructures assembling the elements. After its initial development as an engineering tool mathematicians worked out a rigorous formal framewo
