Detailed Description

Mapping between continuum and discrete domain. Transformation of the differential or integral equations to discrete algebraic equations involving the values of the unknowns at the mesh points. The basis of all numerical methods consists of this transformation of the physical euations into an algebraic, linear or non-linear, systems of equations.
