  1. Greetings,

    I'm thinking about optimizing a 3D-truss structure by Inspire 2017 7305.
    And I would like to know whether it is possible to program the property of materials.
    I'd like to design a part of the structure as a tension wire. So, I'd like to define its compression stiffness as zero, and its tension stiffness as non-zero.

    If it is not possible, I would appreciate if anyone can tell me how to do that (though it may be beyond the scope of this website).


     


  2. Greetings,

    I have a basic question about the optimization in Inspire 2017 7305.

    It is possible to maximize the stiffness as well as the natural frequency of structures in Inspire,
    but how can I decide the weighting function of these two objective functions?

    In general, in such multi-objective optimizations, I think it is necessary to adjust a weighting function. 
    Maybe it is performed automatically by Inspire, but how is it done? On which is focused more - maximization of stiffness, or maximization of natural frequency?

    Thanks in advance.
