  1. the shared file does work. But I think you chose the wrong stress as a constraint. I noticed that after the optimization and have changed the constraint. The optimization is now still running, but it looks like the contraints will not be met. Ergo, I have to redo the first optimization so that there's less lattice and more solid material. To get it to run, please tell me , what changes you made to the model. Hopeful greetings, Julian
  2. I think I only changed the objective to minimize mass. I am currently testing it. In case it works: what change did you make? I have another optimization with a similar problem. Greetings and thank you, Julian
  3. Hello Prakash, I sent the fiels to you via your FileTransferLink. I really hope you can help me. Greetings,
  4. Hello, I was trying to run a lattice optimization. Every time I start the 2nd optimization, Optistruct aborts, printing the following message: *** INTERNAL PROGRAMMING ERROR *** in file "appdrv.F", at location # 1016. **** ABORTING RUN DUE TO AN INTERNAL ERROR **** Can I somehow fix this? Hoping for a quick answer, Julian
  5. Hi, I am having a smiliar problem and was wondering how to alter the simlulation to get it to run on less memory. Is it better to give some guidelines (add parameters) so that the iteration does have some boundaries? Is reducing mesh size the only option? Hoping for a quick answer, Julian
  6. Hello Felix, as I mentioned above (" The fitted Designspace could not be ..."), I already used the fit tool before trying to export it. The Polynurbs function does not really work for me since the desinspace is more or less disc-like and using Polynurbs on it would just make it way more massive than necessary. Regards, Julian
  7. Hi, I saved my optimized part as both step and iges and tried to use them in other programs (Siemens NX and Hyperworks). The fitted Designspace could not be mashed in the other programs because of self intersection, the non-fitted part had the Designspace completely empty when I loaded it into the other programs. Is there a solution for this problem? Sincerely, Julian
  8. Hello, I am currently working on a project for my Thesis and am using Inspire to optimize gears. The attached pic is a screenshot of an optimization where the goal was to minimize mass but keep a SF of 2. The analyzed solution does have a minimal SF of 0.9 though. Why does Inspire not just keep more mass at the place where the SF is too low? Greetings, Julian
