This course aims to teach concepts, fundamental knowledge and implementation of advanced numerical approaches for civil engineering problems analysis. In particular, the lecture details the formulation of numerical approaches including variational methods, which are closely related to the most popular numerical methods, i.e., boundary element methods (BEM) or finite element methods (FEM). Fundamental concepts and detail on some implementation aspects of both BEM and FEM in 1-D and 2-D are taught. Some practical aspects on the BEM and FEM, e.g., model generation, meshing issues, validation and verification, results, documentation, computer programming, and typical examples in civil engineering problems are also given.
This is an entry level graduate course, which is to give introduction to most popular numerical methods (e.g., BEM, FEM) through applications to several civil engineering problems. The emphasis will be on theories, numerical schemes in linear analysis and applications. The course is expected to provide fundamental concepts of computational methods, and more importantly, to lay foundation for students beginning to engage in research projects that involve implementations of engineering problems using numerical methods.
Upon completion of the course, the students will be able to:
1. Describe and apply basic numerical methods for solving civil engineering problems.
2. Understand and explain the relationship among variational methods, weighted residuals, Galerkin methods, FEM, and BEM.
3. Explain theories and numerical schemes of BEM and linear FEM.
4. Develop algorithms and programs of FEM and BEM for simple problems
5. Understand the importance of numerical simulations of engineering problems using advanced numerical methods, particularly civil engineering problems.
