WebJan 13, 2024 · A fully (pseudo-)spectral solver for direct numerical simulations of large-scale turbulent channel flows is described. The solver utilizes the Chebyshev base functions suggested by J. Shen [SIAM J. Sci. Comput., 16, 1, 1995], that lead to stable and robust numerical schemes, even at very large scale. WebMar 29, 2024 · The spectral accuracy is ensured by using high-order global orthogonal basis functions (Fourier, Legendre, Chebyshev first and second kind, Ultraspherical, Jacobi, Laguerre and Hermite), as opposed to finite element codes that are using low-order local basis functions. how do you spell instantWebTo install this package run one of the following: conda install -c spectraldns pyevtk.
