Computational methods nptel

The Finite volume method in computational fluid dynamics is a discretization technique for partial differential equations that arise from physical conservation laws.
These equations can be different in nature, e.g. elliptic, parabolic, or hyperbolic.
The first well-documented
use of this method was by Evans and Harlow (1957) at Los Alamos.
The general equation for steady diffusion can be easily be derived from the general transport equation for property Φ by deleting transient and convective terms.

The methods used for solving two dimensional Diffusion problems are similar to those used for one dimensional problems.
