[Gmsh] Gmsh: Find elements attached to a line and then treat it as new surface or volume

[Sathyanarayan Rao]

Dear gmsh users,


Is it possible within gmsh .geo file to find the elements that are touching a line and then define those

elements as new surface ? I can do this externally after creating a mesh file, but would be interested

if this is achievable before mesh generation.


Something like


Surface{1} =  Elementsof{Line{1}}; or

Volume{1} =  Elementsof{Line{1}};
