An O(n log n) Solution Algorithm for Spectral Element Methods

By I. Lee, P. Raghavan, S. Schofield and P. Fischer


To leverage significant software development effort, general purpose unstructured codes are often used in structured or semi-structured applications. We show that O(n log n) computational complexities, competitive with classic Fourier methods, are achievable for some classes of semi-structured spectral element applications.
