A Family of Even-Order Central-Upwind WENO Schemes with Averaged Downwind and Novel Global Smoothness Indicators
Jiaxi Gu, Bao-Shan Wang, Wai Sun Don +1
We propose a simple yet effective local smoothness indicator for the downwind stencil in central-upwind weighted essentially non-oscillatory (WENO) schemes of even order for hyperb…

A fast computational framework for the linear bond-based peridynamic model
Chenguang Liu, Hao Tian, Wai sun Don +1
Peridynamic (PD) theory is significant and promising in engineering and materials science; however, it imposes challenges owing to the enormous computational cost caused by its non…

Shock Regularization with Smoothness-Increasing Accuracy-Conserving Dirac-Delta Polynomial Kernels
B. W. Wissink, G. B. Jacobs, J. K. Ryan +2
A smoothness-increasing accuracy conserving filtering approach to the regularization of discontinuities is presented for single domain spectral collocation approximations of hyperb…
