Development of hybrid boundary integral-generalized (partition of unity) finite element solvers for scalar problems

The principal contribution of this paper is to prescribe the manner in which one can hybridize boundary integrals with GFEM. In the next section, we shall briefly describe the problem, and then prescribe the manner in which the computational domain may be truncated using a boundary integral. In doing so, we shall deal with both closed region and open region problems. For open region problems like cavity backed antennas, etc, we will be using Nitsche´s method for truncating the domain. The accuracy of the proposed technique will be demonstrated via comparison against analytical data
