  We present a new algorithm to design lightweight cellular materials with
required properties in a multi-physics context. In particular, we focus on a
thermo-mechanical setting, by promoting the design of unit cells characterized
both by an isotropic and an anisotropic behaviour with respect to mechanical
and thermal requirements. The proposed procedure generalizes microSIMPATY
algorithm to a multi-physics framework, by preserving all the good properties
of the reference design methodology. The resulting layouts exhibit non-standard
topologies and are characterized by very sharp contours, thus limiting the
post-processing before manufacturing. The new cellular materials are compared
with the state-of-art in engineering practice in terms of thermo-mechanical
properties, thus highlighting the good performance of the new layouts which, in
some cases, outperform the consolidated choices.
