-Here are the examples in the Gmsh tutorial. These examples are
-commented (both C and C++-style comments can be used in Gmsh input
-files) and should introduce new features gradually, starting with
-t1.geo.
-
-[NOTE: This tutorial does not explain the mesh and post-processing
-file formats. See the FORMATS file for this.]
-
-There are two ways to actually run these examples with Gmsh. (The
-operations to run Gmsh may vary according to your operating system. In
-the following examples, we will assume that you're working with a
-UNIX-like shell.) The first working mode of Gmsh is the interactive
-graphical mode. To launch Gmsh in interactive mode, just type
-
-> gmsh
-
-at the prompt on the command line. This will open two windows: the
-graphic window (with a status bar at the bottom) and the menu window
-(with a menu bar and some context dependent buttons). To open the
-first tutorial file, select the 'File->Open' menu, and choose 't1.geo'
-in the input field. To perform the mesh generation, go to the mesh
-module (by selecting 'Mesh' in the module menu) and choose the
-required dimension in the context-dependent buttons ('1D' will mesh
-all the curves; '2D' will mesh all the surfaces ---as well as all the
-curves if '1D' was not called before; '3D' will mesh all the volumes
----and all the surfaces if '2D' was not called before). To save the
-resulting mesh in the current mesh format, choose 'Save' in the
-context-dependent buttons, or select the appropriate format with the
-'File->Save as' menu. The default mesh file name is based on the name
-of the first input file on the command line (or 'untitled' if there
-wasn't any input file given), with an appended extension depending on
-the mesh format.
-
-[NOTE: Nearly all the interactive commands have shortcuts. Select
-'Help->Shortcuts' in the menu bar to learn about these shortcuts.]
-
-Instead of opening the tutorial with the 'File->Open' menu, it is
-often more convenient to put the file name on the command line, for
-example with:
-
-> gmsh t1.geo
-
-[NOTE: Even if it is often handy to define the variables and the
-points directly in the input files (you may use any text editor for
-this purpose, e.g. Wordpad on Windows, or Emacs on Unix), it is almost
-always more simple to define the curves, the surfaces and the volumes
-interactively. To do so, just follow the context dependent buttons in
-the Geometry module. For example, to create a spline, select
-'Geometry' in the module menu, and then select 'Elementary, Add, New,
-Spline'. You will then be asked (in the status bar of the graphic
-window) to select a list of points, and to click 'e' to finish the
-selection (or 'q' to abort it). Once the interactive command is
-completed, a string is automatically added at the end of the currently
-opened project file.]
-
-The second operating mode for Gmsh is the non-interactive mode. In
-this mode, there is no graphical user interface, and all operations
-are performed without any interaction. To mesh the first tutorial in
-non-interactive mode, just type:
-
-> gmsh t1.geo -2
-
-To mesh the same example, but with the background mesh available in the
-file 'bgmesh.pos', just type:
-
-> gmsh t1.geo -2 -bgm bgmesh.pos
-
-[NOTE: You should read the notes in the file 'bgmesh.pos' if you
-intend to use background meshes.]
-
-Several files can be loaded simultaneously in Gmsh. The first one
-defines the project, while the others are appended ("merged") to this
-project. You can merge such files with the 'File->Merge' menu, or by
-directly specifying the names of the files on the command line. This
-is most useful for post-processing purposes. For example, to merge the
-post-processing views contained in the files 'view1.pos' and
-'view2.pos' together with the first tutorial 't1.geo', you can type
-the following command:
-
-> gmsh t1.geo view1.pos view2.pos
-
-In the Post-Processing module (select 'Post_Processing' in the module
-menu), two view buttons will appear, respectively labeled "a scalar
-map" and "a vector map". A mouse click on the name will toggle the
-visibility of the selected view, while a click on the arrow button on
-the right will provide access to the view's options. If you want the
-modifications made to one view to affect also all the other views,
-select the 'Apply next changes to all views' or 'Force same options
-for all views' option in the 'Tools->Options->Post-processing' menu.
-
-[NOTE: All the options specified interactively can also be directly
-specified in the ASCII input files. All available options, with their
-current values, can be saved into a file by selecting 'File->Save
-as->Gmsh options', or simply viewed by pressing the '?' button in the
-status bar. To save the current options as your default preferences
-for all future Gmsh sessions, use the 'Tools->Options->Save' button.]
-
-
-OK, that's all, folks. Enjoy the tutorial.

-<I><FONT COLOR="#B22222">// All geometry description in Gmsh is made by means of a special
-</FONT></I><I><FONT COLOR="#B22222">// language (looking somewhat similar to C). The simplest construction
-</FONT></I><I><FONT COLOR="#B22222">// of this language is the 'affectation'.
-</FONT></I>
-<I><FONT COLOR="#B22222">// The following command (all commands end with a semi colon) defines
-</FONT></I><I><FONT COLOR="#B22222">// a variable called 'lc' and affects the value 0.007 to 'lc':
-</FONT></I>
-lc = 0.007 ;
-
-<I><FONT COLOR="#B22222">// This newly created variable can be used to define the first Gmsh
-</FONT></I><I><FONT COLOR="#B22222">// elementary entity, a 'Point'. A Point is defined by a list of four
-</FONT></I><I><FONT COLOR="#B22222">// numbers: its three coordinates (x, y and z), and a characteristic
-</FONT></I><I><FONT COLOR="#B22222">// length which sets the target mesh size at the point:
-</FONT></I>
-Point(1) = {0, 0, 0, 9.e-1 * lc} ;
-
-<I><FONT COLOR="#B22222">// The mesh size is defined as the length of the segments for lines,
-</FONT></I><I><FONT COLOR="#B22222">// the radii of the circumscribed circles for triangles and the radii
-</FONT></I><I><FONT COLOR="#B22222">// of the circumscribed spheres for tetrahedra, respectively. The
-</FONT></I><I><FONT COLOR="#B22222">// actual distribution of the mesh sizes is obtained by interpolation
-</FONT></I><I><FONT COLOR="#B22222">// of the characteristic lengths prescribed at the points. There are
-</FONT></I><I><FONT COLOR="#B22222">// also other possibilities to specify characteristic lengths:
-</FONT></I><I><FONT COLOR="#B22222">// attractors (see t7.geo) and background meshes (see bgmesh.pos).
-</FONT></I>
-<I><FONT COLOR="#B22222">// As can be seen in the previous definition, more complex expressions
-</FONT></I><I><FONT COLOR="#B22222">// can be constructed from variables. Here, the product of the
-</FONT></I><I><FONT COLOR="#B22222">// variable 'lc' by the constant 9.e-1 is given as the fourth argument
-</FONT></I><I><FONT COLOR="#B22222">// of the list defining the point.
-</FONT></I><I><FONT COLOR="#B22222">//
-</FONT></I><I><FONT COLOR="#B22222">// The following general syntax rule is applied for the definition of
-</FONT></I><I><FONT COLOR="#B22222">// all geometrical entities:
-</FONT></I><I><FONT COLOR="#B22222">//
-</FONT></I><I><FONT COLOR="#B22222">// "If a number defines a new entity, it is enclosed between
-</FONT></I><I><FONT COLOR="#B22222">// parentheses. If a number refers to a previously defined entity,
-</FONT></I><I><FONT COLOR="#B22222">// it is enclosed between braces."
-</FONT></I><I><FONT COLOR="#B22222">//
-</FONT></I><I><FONT COLOR="#B22222">// Three additional points are then defined:
-</FONT></I>
-Point(2) = {.1, 0, 0, lc} ;
-Point(3) = {.1, .3, 0, lc} ;
-Point(4) = {0, .3, 0, lc} ;
-
-<I><FONT COLOR="#B22222">// The second elementary geometrical entity in Gmsh is the
-</FONT></I><I><FONT COLOR="#B22222">// curve. Amongst curves, straight lines are the simplest. A straight
-</FONT></I><I><FONT COLOR="#B22222">// line is defined by a list of point numbers. For example, line 1
-</FONT></I><I><FONT COLOR="#B22222">// starts at point 1 and ends at point 2:
-</FONT></I>
-Line(1) = {1,2} ;
-Line(2) = {3,2} ;
-Line(3) = {3,4} ;
-Line(4) = {4,1} ;
-
-<I><FONT COLOR="#B22222">// The third elementary entity is the surface. In order to define a
-</FONT></I><I><FONT COLOR="#B22222">// simple rectangular surface from the four lines defined above, a
-</FONT></I><I><FONT COLOR="#B22222">// line loop has first to be defined. A line loop is a list of
-</FONT></I><I><FONT COLOR="#B22222">// connected lines, a sign being associated with each line (depending
-</FONT></I><I><FONT COLOR="#B22222">// on the orientation of the line).
-</FONT></I>
-Line Loop(5) = {4,1,-2,3} ;
-
-<I><FONT COLOR="#B22222">// The surface is then defined as a list of line loops (only one
-</FONT></I><I><FONT COLOR="#B22222">// here):
-</FONT></I>
-Plane Surface(6) = {5} ;
-
-<I><FONT COLOR="#B22222">// At this level, Gmsh knows everything to display the rectangular
-</FONT></I><I><FONT COLOR="#B22222">// surface 6 and to mesh it. But a supplementary step is needed in
-</FONT></I><I><FONT COLOR="#B22222">// order to assign region numbers to the various elements in the mesh
-</FONT></I><I><FONT COLOR="#B22222">// (the points, the lines and the triangles discretizing points 1 to
-</FONT></I><I><FONT COLOR="#B22222">// 4, lines 1 to 4 and surface 6). This is achieved by the definition
-</FONT></I><I><FONT COLOR="#B22222">// of Physical entities. Physical entities will group elements
-</FONT></I><I><FONT COLOR="#B22222">// belonging to several elementary entities by giving them a common
-</FONT></I><I><FONT COLOR="#B22222">// number (a region number), and specifying their orientation.
-</FONT></I><I><FONT COLOR="#B22222">//
-</FONT></I><I><FONT COLOR="#B22222">// For example, the two points 1 and 2 can be grouped into the
-</FONT></I><I><FONT COLOR="#B22222">// physical entity 1:
-</FONT></I>
-Physical Point(1) = {1,2} ;
-
-<I><FONT COLOR="#B22222">// Consequently, two punctual elements will be saved in the output
-</FONT></I><I><FONT COLOR="#B22222">// files, both with the region number 1. The mechanism is identical
-</FONT></I><I><FONT COLOR="#B22222">// for line or surface elements:
-</FONT></I>
-Physical Line(10) = {1,2,4} ;
-MySurface = 100;
-Physical Surface(MySurface) = {6} ;
-
-<I><FONT COLOR="#B22222">// All the line elements which will be created during the mesh of
-</FONT></I><I><FONT COLOR="#B22222">// lines 1, 2 and 4 will be saved in the output file with the region
-</FONT></I><I><FONT COLOR="#B22222">// number 10; and all the triangular elements resulting from the
-</FONT></I><I><FONT COLOR="#B22222">// discretization of surface 6 will be given the region number 100.
-</FONT></I><I><FONT COLOR="#B22222">//
-</FONT></I><I><FONT COLOR="#B22222">// If no physical groups are defined, all the elements in the mesh are
-</FONT></I><I><FONT COLOR="#B22222">// directly saved with their default orientation and with a region
-</FONT></I><I><FONT COLOR="#B22222">// number equal to their elementary region number. For a description
