While motivated by a particular application, the work described is quite generalizable. Although present in the literature, Simulated Annealing for the synthesis of porous media has met with limited success due to computational costs and practical modelling constraints. An alternative method based on hierarchical annealing will be presented. Inherently multiscale, such approaches may dramatically reduce the computational cost. Energy functions (based on e.g. chord-length distribution) in a hierarchy allow separately treating structures of different length scales, reducing convergence issues for samples with multiple natural scales. Such an approach naturally leads to methods of explicitly multiscale modelling.
