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