[Gmsh] GMSH - excluding some common nodes from Meshing

[koushik gattu]

Hello,

Recently, I have started using GMSH for my project where i need to mesh a
simple geometry and read its nodes using Matlab.

I have everything working except some issues with the meshing..

My Geometry is very simple: I have circle inside a rectangle..I have
defined plane surface and physical groups for this structure. I would like
to know the list of nodes on the boundary of rectangle and inside
rectangle(but outside circle)..

I noticed there are some common nodes for both the structures..is there any
way in Gmsh to not to have common nodes?

I have attached my msh and geo file to this email..

Thank you so much in advance.

Thank you,
K
