Computational mechanics is a constantly growing field with impact on both science and industry in all areas of engineering. It is concerned with solving mechanical problems on the basis of numerical approximation methods, involving discretization of the underlying equations in both space and time. Nowadays, related skills are indispensable in civil and mechanical engineering, for the design of automobiles and spacecrafts, for developments in biomechanics and micro-electro-mechanical systems. Virtually, all technical disciplines make use of the fast progress in this area.
