• Syllabus

The course objective is to give students insight and skills with computational methods as a means of investigating problems in mechanical engineering. While much of the course is based on numerical methods for differential equations, the examples and homeworks will be mechanics based, so that students can understand the deep connections between the behavior of mechanical systems and their numerical counterparts. Topics will include numerical solution of multidimensional boundary value problems (e.g., the heat equation, advection-diffusion, and Stokes) and initial value problems (e.g., unsteady variants of the same). By the end of the course, students will be able to identify potential sources of error and instability and be able to estimate computational costs/feasibility for these schemes. Finally, they should be able write and test (!) code to solve computational mechanics problems.
