Hi everyone,
I want to generate a structured mesh for a 5 vertices polygon as the
attached picture.
[image: image.png]
I used the code below to specify the points, lines and generate the
surface, but I need a structured mesh.
I know that I can reach this dividing the polygon in two polygons with 4
vertices each. However, I'm looking for other solutions.
SetFactory("OpenCASCADE");
//+
Point(1) = {0, 0, 0, 1.0};
//+
Point(2) = {0, 200, 0, 1.0};
//+
Point(3) = {100, 200, 0, 1.0};
//+
Point(4) = {100, 100, 0, 1.0};
//+
Point(5) = {50, 0, 0, 1.0};
Point(6) = {100, 0, 0, 1.0};
Line(1) = {1, 2};
//+
Line(2) = {2, 3};
//+
Line(3) = {3, 4};
//+
Line(4) = {4, 5};
//+
Line(5) = {5, 1};
//+
//+
Transfinite Curve {1, 2} =5;
Transfinite Curve {3 : 5} = 3;
//+
Curve Loop(1) = {1, 2, 3, 4, 5};
//+
Surface(1) = {1};
//+
Transfinite Surface {1} = {1,2,3,6};
//+
Recombine Surface {1};
Thanks,
Pollyana.
