摘要: Under the governing equations of hyperbolic heat transfer, energy propagates through a medium as wave with sharp discontinuities at front. The use spectral methods to solve such problems numerically results in solution which strong numerical oscillations are present due Gibbs-Wilbraham phenomenon. It is demonstrated that spectrally accurate can still be obtained via postprocessing technique.
