hello,
I'm facing a problem during Hyperfea optimization process combined with FEA constraints implementation related to the spars of a wingbox . More in detail, although max displacement target value (Tmax=945 mm) is achieved after 5 iterations (943.19 mm)the following iterations don't seem to converge to above mentioned value instead continue to reduce max displacement value by increasing membrane stiffness and mass of affected components (spars caps). In attachment you can find some pictures which i hope will help you to better understand the problem.

thank you

Eugenio
