Hello,
I am working on a project where lattice optimization will be performed on a part that will eventually be printed using additive manufacturing. From what I understand, after performing a topology optimization using optistruct, the elements with a density between UB and LB will be converted into lattice structure. Based on some trial analysis, it appears that each element is converted into it's own lattice 'unit cell'. For a fine mesh this presents a problem as the lattice structure will be too small to print. Is there any way to continue using a fine mesh for accuracy but to have a larger lattice created?
I can also use a larger mesh, but with the complex geometry I suspect the optimization will be significantly less accurate.
