A highly efficient and accurate divergence-free spectral method for curl-curl equation in two and three dimensions

Lechang Qin, Changtao Sheng, Zhiguo Yang

In this paper, we present a fast divergence-free spectral algorithm (FDSA) for the curl-curl problem. Divergence-free bases in two and three dimensions are constructed by using the…
