[Gmsh] unstructured mesh

[jeremy theler]

what about taking a look at projects/small_fem/tests/poisson/square.geo ?

cl = 0.5;
l  = 1;

Point(1) = {+l, -l, 0, cl};
Point(2) = {+l, +l, 0, cl};
Point(3) = {-l, +l, 0, cl};
Point(4) = {-l, -l, 0, cl};

Line(1) = {1, 2};
Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 1};

Line Loop(1)     = {1, 2, 3, 4};
Plane Surface(1) = {1};

//Recombine Surface {1};

Physical Line(5) = {3};
Physical Line(6) = {1};
Physical Surface(7) = {1};
