Gmsh is dimensionless (like say a pocket calculator, a spreadsheet, or a Fortran compiler is); the length-units are whatever you like. This has to be taken into account in whatever you do with the mesh once you've generated it in Gmsh. I think the 1:1 button on the GUI only affects the `scale' of the view, not the model itself. Try zooming in or out and then clicking it to see what I mean. I believe the Dilate command of the Geometry model <http://geuz.org/gmsh/doc/texinfo/gmsh_6.html#SEC37> might be of interest if you do want to scale things, but I haven't tried it myself. _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
