I have a mesh where the Wire surface should be 1.606793E+09 m and the whole
Surface (wire+fluid) should have a radius of 12.915E-06m am I doing
something wrong? because I dont get the expected results? PS. the cellsize
should decrease the more far it is from 0,0 thanks!

cellSize = 1E-07;
cellSize2 = 5E-7;
cellSize3 = 1E-5;
cellSize4 = 1E-4;
radius = 12.915E-06;
fluidradius = 5E-04;

Point(1) = {0, 0, 0, cellSize};
Point(2) = {radius, 0, 0, cellSize};
Point(3) = {0, radius, 0, cellSize};
Point(4) = {fluidradius, 0, 0, cellSize4};
Point(5) = {0, fluidradius, 0, cellSize4};

Point(6) = {fluidradius*0.33, 0, 0, cellSize2};
Point(7) = {0, fluidradius*0.33, 0, cellSize2};
Point(8) = {fluidradius*0.66, 0, 0, cellSize3};
Point(9) = {0, fluidradius*0.66, 0, cellSize3};
Circle(1) = {3, 1, 2};
Line(2) = {1, 2};
Line(3) = {1, 3};
Line(4) = {2, 4};
Line(5) = {3, 5};
Circle(6) = {5, 1, 4};
Line Loop(8) = {1, -2, 3};
Plane Surface(8) = {8};
Line Loop(10) = {4, -6, -5, 1};
Plane Surface(10) = {10};
Physical Surface("Wire") = {8};
Physical Surface("Fluid") = {10}
