Hi Guys, I'd like to share "Tips and Tricks" regarding Lattice Design and the NonDesign Space. First to mention: Please keep Inspire updated - we introduced Lattice in 2017.3 but the last few months, we put a lot of effort to increase performance and stability! ATM (April 2018), 2018.1 is best to work with! If you are unhappy with the "resolution" of your nonDesign spaces after a lattice optimization - you can manually force the nondesignspace (per part) to use smaller elementsize inside the model configuration: Comparison: Before: After: Furthermore, you can create a smoothed lattice before you export it as an STL: Regards, Felix
Hi, Is there anyway to integrate Additive Manufacturing constraints for topology optimization in optistruct? I would like to add constraints such as maximum overhang angle, minimum number of support structure, etc... I would also like to determine the best build direction. Thank you
Good Afternoon, I've seen "Material Orientation Method" topic from @Ameydholam, however mine is slightly different that's why i created this new topic. So, my main goal is to evaluate the "influence/effect" of the printing direction considering an orthotropic material (MAT9ORT). My problem arises at the very start, considering that i used CHEXA or CPENTA I can never change material direction in accordance to the perpendicular shell element. I created a small example where this is visible, on the first image it's represented the 2D Mesh (Orange and Red) and the 3D Mesh (Blue and White), on the second image it's the material orientation and it's visible that the component that has no 2D shell on that direction is not able to change to the desired direction. Shell elements only have in-plane orientations, that part is clear, however when the solid part is created shouldn´t i be able to give any desired orientation to the solid element? Attached to this follows the model. Hope that anyone can help me. Thanks. material_direction_test.fem
Hello, I'm currently working on a university project which is investigating the use of topology optimisation for additive manufacturing (AM). One of the side effects of some AM processes is that built components will exhibit different mechanical properties along each axis. This is dependent upon orientation of the design within the AM build chamber. In respect to Selective Laser Melting or Electron Beam Melting in Titanium-64, could anybody recommend an approach (within Optistruct) which could account for the varying mechanical properties? Alternatively, if anybody knows of a way to heat treat AM parts so that the anisotropy/orthotropy is negated during optimisation, that too would be helpful. Any help with this issue would be hugely appreciated! Thanks, Dan Walton
