[Gmsh] 2D meshing without changing the outline

[Bartek Grychtol]

Hi All,

I would like to mesh a surface from line loops but such that no nodes would
be added or moved on the loops (the boundary/outline) themselves.
Is this possible?

In 3D, by accident or design, I achieve the same by specifying a Surface
Loop from an STL file as in:
Merge "tmp.stl";
Surface Loop(1) = {1};
Volume(1) = {1};
Physical Volume('object') = {1};
Mesh.Algorithm3D=4;
Mesh.Optimize=1;

Perhaps, even if there is no command to achieve this, there are conditions
under which it will happen? Any advice will be much appreciated!
Thanks in advance.

Best wishes,

Bartek
