Modelling of Nonlinear Behaviour
Nonlinearity has been encountered in all realistic problems of science. The aim of this paper is thus to investigate the nonlinear behaviour of various real-world processes using the most common numerical based approaches. Since the nonlinearity in representing various models is the most common and the most realistic behaviour in nature, we have concentrated on the illustration of the issue using various effective numerical methods. The illustrative experiments have mainly been selected from fluid dynamics, in use of modelling particular topics, the advection-diffusion processes. The provided results are seen to properly represent the behaviour of the models. The present work is believed to provide a better understanding of the importance of modelling a realistic process using a numerical perspective. This endeavour could also help in targeting beginner groups in various areas for numerical modelling.
