Lattice modelling

User: "Altair Forum User"

Hi, I was wondering if there is any way to convert a solid part into a lattice structure without any optimization. In my analysis, I am considering a cylinder which it has an outer layer made of lattice. To perform the analysis, I want to have a lattice structure in outer surface. so would it be possible to model a lattice part in Hyperworks?

Thank you,

Soraya

    Hi Soraya,

     

    Maybe it is possible, but there is every chance that you will miss the best design... :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'> 

     

    I personally prefer doing an optimization run to get the lattice in HyperWorks.

    Thank you Prakash. I just wonder if you know that if it is possible to define a constraint for strain energy in optimization by optistruct?

    Hi Soraya,

     

    Right now there is no response is available for strain energy. If your objective is to stiffen the structure, you can try to use 'frequency' as a response. Place a lower bound on that frequency response to stiffen the structure.

    Thank you Prakash. I realized how to solve my problem.

     

    Best,
