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
Maybe it seems easy, but it is a hard question for a new starter like me. I have already successfully meshed the objects into triangular grids(2D automesh). but when I checked the equivalence, I found out that there existed some free edges. and then I clicked on the button "equivalence". Then after a long time, it may have finished equivalence. But when I rechecked the free edges. There are still many free edges. What should I do? As I understand it, free edges means edges that are not shared with two triangles. So some nodes should be merged into one. I used to use Patran to mesh grids. What i have done is based on my experience of using patran. Thank you!
I have a mesh in component1 and another mesh in component2. Is there a way to do a node equivalencing operation from comp1 to comp2? What I mean is, while I do this operation, I don't want the nodes on comp1 to equivalence to nodes on comp1 (no node equivalencing on the same component) Thanks!
