flac2d flac2d geoBrendan (Geotechnical) (OP) 28 Sep 15 14:49 hello guys, I have been studying flac2d for some time now. can anybody help me with how to draw horizontal layers in both flac and flacslope? thank you very much RE: flac2d SixDegrees (Geotechnical) 15 Oct 15 17:21 Hi geoBrendan, There's a couple of ways that you can manipulate the FLAC grid to get the mesh geometry. 1. Try generating the mesh using the x,y coordinates if the bottom, left, top and right of the layers you need. FLAC actually has a virtual builder to help with this 2. You can also change the coordinates of an already generated mesh to conform to a line using the Genline command. The Genline command can be executed using the Alter->Shape feature in the GUI/ It takes a bit of practice but horizontal layers are probably the simplest (simple being relative concept when using FLAC) geometry in FLAC because the grid is usually orientated horizontal and vertically. Good luck, SixDegrees RE: flac2d geoBrendan (Geotechnical) (OP) 16 Oct 15 10:07 thank you very much SixDegrees. I actually meant to ask about vertical layers.
