Abstract

The purpose of this paper is to introduce a BDDC method for vector field problems discretized with the lowest order Raviart-Thomas finite elements. Our method is based on a new type of weighted average, a deluxe scaling, developed to deal with more than one variable coefficient. Numerical experiments show that the deluxe scaling is robust and more powerful than traditional methods.
