% MakeMeshData2nd is a script that builds two circular  
% meshes for 2D EIT Package. Denser mesh (mesh 2) is for forward computations and
% a coarse mesh (mesh 1) for inverse computations. See also
% meshgen_eit2d.m, MakeElement2nd and MakeNode. 




S=2.5; % Length of the electrode.
N=16;  % Number of the electrodes.
r=14;  % Radius of the circle.
style='s'; % 's' for the structured mesh and 'u' for the unstructured mesh
