  1. 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. Nathalie
  2. Hi everyone, I am new to lattice optimization, and i want to control the diameter beam size and have a better understanding of CLEAN option. If i understood well, CLEAN option can be used with MinRad to delete beams under the radii defined in MinRAD. - When i don't touch the lattice parameter panel, CLEAN is set to YES by default and clean beams with very small radii (E-05 mm) at the end of phase 2 - When i use only MinRad (2mm) and CLEAN set to NO, it get all the beams above the radius defined. - But when i use Minrad with a radius of 2mm and CLEAN set to YES, it has trouble creating a feasible design. Is it because CLEAN option only works with very small radii ? It doesn't simply delete beam under MinRad in the end of optimization? For information, my mesh size is 5 cm, and my objectif is to create à structure with big enought beam, but with less beam without changing the mesh. Thank you in advance.
