Abstract
A method for implementing divergence constraints in the finite element method is given. This method yields a linearly independent, sparse set of constraints for a mesh of brick elements. The method is used to obtain the resonant frequencies of rectangular cavities with perfectly conducting walls. There is good agreement with exact values and there are no spurious modes.
