The present contribution reports on preliminary results of enhancing the approximation space of the Finite Element Method by means of pre-generated displacement fluctuation fields. The formulation builds on the Wang tile based compression of investigated microstructures and expands the application potential of the tiling compression into numerical methods. Enrichment functions are precomputed as responses of the compressed system to a set of load cases and synthesized analogously to the synthesis of the microstructure. The performance is illustrated with a two-dimensional linear diffusion problem.
