// label "My third line (physical id 5)". And finally, all the triangular
// elements resulting from the discretization of surface 6 will be given an
// automatic physical id associated with the label "My surface").

// Note that if no physical entities are defined, then all the elements in the
// mesh will be saved "as is", with their default orientation.
// Starting with Gmsh 3.0, models can also be built using constructive solid
// geometry. Instead of the built-in geometry kernel, you need to use the
// OpenCASCADE kernel:
//
// SetFactory("OpenCASCADE");
//
// In addition to the "bottom-up" geometry commands, you can now use "top-down"
// commands, like e.g.
//
// Rectangle(2) = {.2, 0, 0, 0.1, 0.3};
//
// See tutorial/t16.geo for an example, and demos/boolean for more.
