Engineering applications are becoming more and more complex. Consequently, the theory required to analyse corresponding systems becomes increasingly complicated as well. Experimental investigations are often too complex, too risky, or too costly. Computational Engineering (CE), including computer based modelling, analysis, simulation, and optimisation, is a cost effective and efficient alternative to investigate engineering applications and to engineer new technical solutions. It enables the creation of scalable digital models to support research, development, design, construction, evaluation, production, and operation of engineering applications. It allows optimal strategies to be found, which address key issues in future technical developments for the economy and society, in the areas such as energy, health, safety, and mobility.
