Question #691976 on Yade changed: https://answers.launchpad.net/yade/+question/691976 Status: Open => Answered Jan Stránský proposed the following answer: 1) of course there are rules :-) specifically for faces (where is your problem), the numbers are indices of edges, in counter-clockwise order (seen from the resulting normal direction). In your case, your first face is > 1 2 5 your 1st, 2nd and 5th edges are > 1 2 > 1 3 > 2 4 I.e. you tell gts to create triangle from vertices number 1, 2, 3 and 4, which is the problem. 2) there are plenty of options. First, you need the vertices and triangles: - "by hand" (like the simple example) - programatically "by hand", e.g. cylinder should be ok to triangulate "manually" - using some external meshing software - from existing file (e.g. from STL file format you can convert to GTS using stl2gts utility from libgts-bin Ubuntu package) Once having the data, you can: - create the gts file "by hand" - create the file programatically by yourself - create the gts structure using gts.Vertex, gts.Edge, gts.Surface and finally gts.Surface.write method [3] - save it to another format and convert it to gts (e.g. stl2gts) cheers Jan [3] https://woodem.org/woo.gts.html -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
