Hello,

I am new to gmsh. I succeeded in making some 2D meshes and computations, but I had strange behaviors at wall. Looking at the mesh, it appeared that lines and circles do not connect correctly. Here is a very simple example:

Point( 1) = {  22.25000, 57.57847, 0.0, 1};
Point( 2) = {  55.87660, 24.05100, 0.0, 1};
Point( 3) = {  68.14965, 20.75000, 0.0, 1};
Point( 4) = { 185.03900, 52.32200, 0.0, 1};
Point(10) = {  64.83803, 33.02000, 0.0, 1};
//
Line(1) = {1, 2};
Circle(2) = {2, 10, 3};
Line(3) = {3, 4};
Line Loop(1) = {1, 2, 3};

When zooming at point 3, circle and line do not connect when they are defined with the same point. Is it related to some tolerance parameter? Can anybody help ?

Two good reasons to close this thread:
1- it is related to gmsh use...
2- the answer was obvious: it is the rounding error in the input.
Sorry.
