The paper presents the idea of coupled multiphysics computations. It shows the concept and presents some preliminary results of
static coupling of structural and fluid flow codes as well as biomimetic structural optimization. The model for the biomimetic optimization
procedure was the biological phenomenon of trabecular bone functional adaptation. Thus, the presented structural bio-inspired optimization
system is based on the principle of constant strain energy density on the surface of the structure. When the aeroelastic reactions are
considered, such approach allows fulfilling the mechanical theorem for the stiffest design, comprising the optimizations of size, shape and
topology of the internal structure of the wing.
