Lattice diameter before sizing optimization

Hi,

I've been learning how to use optistruct in lattice optimization and I've come across this tutorial.

 

 

After following the tutorial, I noticed once the initial lattice is generated (before sizing optimization) that strut has it's unique diameter. Is there any reference on how the diameters are determined initially?

 

Thanks

    Hi Rahul,
    Thanks for the reply. I've checked the document, but it doesn't specify the exact way to determine the beam diameters. On page 5, it says the diameters are proportional to the density value. So if I have an edge between two elements and each had a different density value (say 0.4 and 0.5). How would I determine the diameter at each node?

    Thanks
