Set a Size optimization desvar automatically with large amount of Beam

Recommended Posts

Hello everyone, 

 

I did a 1D topology optimization of a lattice structure (composed of a large amount of PBeamL elements).

 

I want now to perform a Size Optimization of each beam section. Is it possible to generate automatically the design variables (and design variables property relationship), of the lattice structure at this point ? 

 

Thank you in advance for the help.

Hi,

 

if you have correctly set up the lattice optimization,  the design variables (and design variables property relationship) should be generated automatically after the first phase. Just import the modelname_lattice.fem file at the start of the second phase.

 

I recently made a video on lattice optimization, which you may find useful:

 

Also refer to tutorial OS-T: 3300 Lattice Optimization Process
