Numerical Analysis

EAS439 Numerical Analysis introduces students to fundamental concepts, programming skills, and software applications of numerical analysis for solving aerospace engineering problems. The first part of the course prepares students with pre-requisite knowledge and programming skills. Fundamental concepts of linear algebra are introduced to pave the foundation. A short introduction to computer programming for numerical analysis is presented to equip students with the necessary skills for algorithm implementation. The second part of the course covers fundamental numerical methods. Topics covered include approximations and the Taylor series, numerical error analysis, numerical solution of linear systems of algebraic equations, numerical solution of nonlinear algebraic equations, regression and interpolation techniques, numerical differentiation and integration, as well as the numerical solution of boundary-value problems. This part includes laboratory tutorials for programming implementation of numerical algorithms. The third part of the course introduces numerical simulation techniques for two types of engineering problems in aerospace engineering, i.e., structural analysis and computational fluid dynamics. The finite Difference Method (FDM) is introduced in the context of model equations in fluid mechanics and thermodynamics. The finite Element Method (FEM) is introduced with the formulations of bar element, beam element, and plane stress element. Laboratory tutorials are conducted for hands-on training of solving practical engineering problems using simulation software.
