Rizzo 0 Report post Posted September 17, 2014 Hello at all, during a topology optimization of a wireframe of a student racecar the check before optimizing gives the following error: A fatal error has been detected during input processing: *** ERROR # 6001 *** Two of the vectors defined on DTPL card 1 are aligned. I don´t know what to do now. At the end of this text i add a dropbox link to my hm-file, so maybe someone of you can have a look and give me tipps to solve my prob. I guess it could be the connection between the beams (1D) and the design space (solid). i equivalenced them with the equivalence function (in menu SHIFT+F3) in compliance with a small warpage. Maybe the local vectors of the beams are incorrect now.I don´t have any idea. I hope there is someone can help me. greets, Thomas https://www.dropbox.com/s/evz55axqz5ru4r0/TEST_MOdell_7.hm?dl=0 Quote Share this post Link to post Share on other sites
Guest Report post Posted September 17, 2014 Hi Rizo, You have defined the same node location for first and second node in pattern grouping. Please choose another node for either first or second node. Quote Share this post Link to post Share on other sites
