Hi there,

Every time I generate a mesh with gmsh in 3D, there will be 1D and 2D elements 
listed in the .msh file. However, for my simulation, I don't really need the 1D 
and 2D elements. Is there a way to get rid of them?

In addition, I am just wondering what roles the 1D and 2D elements are playing. 
If I have second order curved elements, by opening a .msh file with 1D and 2D 
elements, I can see the curved lines behind the mesh. However, if I remove the 
1D and 2D elements by hand, I am still able to get the mesh but the curved 
lines woul
d disappear. How would the 1D and 2D elements affect this? 

Thank you very much.
Shi
