This work uses the eight-noded quadrilateral finite element method to study the eigen analysis for several energy issues in the multiply-connected domain. The computing of eigenvalues across circular and multiply-connected curved domains is one of its applications, this method makes advantage of an excellent, eight-noded, quadrilateral automatic mesh generator created with MAPLE-18 software, this method makes use of a superb FEM process as seen by the examples provided, the proposed technique provides efficient numerical solutions for a range of problems and increases the accuracy of the numerical solution of eigenvalues that occur in a number of electromagnetic applications due to the reduced curvature loss, the validity of the current concept is demonstrated by these issues, the numerical results for the example situations using the suggested approach are quite similar to the best-published results.Refference:
