The contribution presents the essential steps for the extension of the well‐known FE 2 method by elements from variational design sensitivity analysis. The derived sensitivity information for a given structure can be used to suggest improved designs using methods for structural optimisation with objective functions, constraints and design variables on multiple scales.
