Spectral method phase field

WebThis Sliding Window Phase Matching (SWPM) method generates the spectral amplitude on an arbitrary grid in BA and IH, e.g., along the coordinate axes. To illustrate, we show both SWPM and STFT methods applied to operational MetOp-A data. For SWPM we use a constant window in the BA-dimension, whereas for STFT we use a conventional constant … WebMay 6, 2024 · Fourier spectral methods for phase field fracture modelling of CMCs - IOPscience This site uses cookies.
