Predicting process–structure and structure–property relationships are the key tasks in materials science and engineering. Central to both research directions is the internal material structure. In the case of metallic materials for structural applications, this internal structure, the microstructure, is the collective ensemble of all equilibrium and nonequilibrium lattice imperfections. Continuum models to derive process–structure and structure–property relationships are based on two ingredients: 1) quantitative state variables that capture the essential features of the material's state and 2) kinetic equations for the state that describe its evolution under load. Successful models, that is, models that are of practical use, depend on state variables and corresponding evolution laws that are sufficiently representative for the microstructure and that are able to describe the phenomena of interest. The development of software tools capable to integrate these different aspects to get a holistic view of process–structure–property relationships requires joint efforts from specialists in different disciplines and a long‐term perspective. The Düsseldorf Advanced Material Simulation Kit (DAMASK) is such a tool. In this overview article published on the occasion of Advanced Engineering Materials' 20th anniversary, some representative application examples which demonstrate how DAMASK can be used to study metallic microstructures at different length scales are presented.
