**Preface to "Numerical Modelling and Simulation of Metal Processing"**

The service properties of materials strongly depend on their chemical composition, as well as their processing conditions. The specific applications and the optimization of thermal and thermomechanical processes enable the conservation of processes, the treatment of new alloy variants, and the realization of materials with special properties. The numerical simulation of metal processing, coupled with the modelling of the structural evolution, reduces the need for time- and cost-expensive tests at lab and industrial scale. Here, multiscale modelling is considered as an appropriate means to describe the development of the nano-, micro-, and macrostructure and, hence, to determine the local material properties.
