Hello,
I make a mesh with the following geo file:
l = 1.0;
h = 1.0;
n = 40;
m = 40;
Point(1) = { 0, 0, 0 };
Point(2) = { l, 0, 0 };
Line(1) = {1,2};
Transfinite Line{1} = n+1;
Surf[] = Extrude{0,h,0} { Line(1); Layers{m}; };
The resulting mesh is a 2D mesh made of triangles
obtained by dividing a square by a diagonal, all diagonals
having the same direction.
I would like to know if there is a method I can use
in the geo file to split the square by the other diagonal
and a method to split the square in 4 triangles
still with the diagonals.
Thank you.
