CREATECIRCULARMESH Creates a circular finite element mesh

 USAGE:

       vmcmesh = createCircularMesh(radius, dh)

 DESCRIPTION:

       Creates a circular finite element mesh (2D)

 INPUT:

       radius      - Total radius of the circle [mm]
       dr          - Separation of each node in radius [mm]

 OUTPUT:

       vmcmesh     - Resulting circular mesh
