Difficulty in LGR during creating two circles shared one center
Hello,
SetFactory("OpenCASCADE");
//+
Point(1) = {0, 0, 0};
//+
Point(2) = {5, 0, 0};
//+
Point(3) = {5, 5, 0};
//+
Point(4) = {0, 5, 0};
//+
Line(1) = {1, 2};
//+
Line(2) = {2, 3};
//+
Line(3) = {3, 4};
//+
Line(4) = {4, 1};
//+
Circle(5) = {2.5, 2.5, 0, 0.1, 0, 2*Pi};
//+
Circle(6) = {2.5, 2.5, 0, 0.2, 0, 2*Pi};
//+
Curve Loop(1) = {4, 1, 2, 3};
//+
Curve Loop(2) = {5};
//+
Curve Loop(3) = {6};
//+
Plane Surface(1) = {1, 2};
//+
Plane Surface(1) = {2, 3};
Mesh.MeshSizeFromCurvature = 100;
Mesh.Algorithm = 2;
Mesh.MeshSizeMax = 0.05;
Mesh.Smoothing = 3;
- I don't know why the outer circle is not LGR by the elements. Can anyone help me with that?
- The area between two circles should be uniform mesh size Thank you
