    How is the cost of your material calculated? if it is calculated per mass i.e. per kg, then you can optimize the part with minimize mass as the objective.

    Hi Rahul,

     

    e.g. two Material Truss: Steel: Price 20 $/ Kg,  Alu: Price 15 $ / Kg:

     

    Obj-Fkt: f (X) = mass_steel * 20 + mass_alu * 15 .

    Please go through the tutorial in HyperStudy where material cost and volume are used as responses. That may some how useful for you image/emoticons/default_smile.png' alt=':)' srcset='/emoticons/smile@2x.png 2x' width='20' height='20'>
