Abstract :
The application of the finite element method to electromagnetic problems often yields a sparse, positive definite, symmetric. and very high order system of linear algebraic equations. Solving such a system is a major computational task. The SSOR preconditioner is applied to vector FEM for analysis of large 3-dimensional Helmholtz vector equations in electromagnetic boundary value problems.
