摘要
将简化的WENO重构方法应用到了一个基于坏单元指示子的h自适应RKDG算法,并从数值上证明了这个算法能有效提高间断附近的数值解质量。数值试验还表明这个重构方法对一维h自适应网格也能很好地消除数值振荡,同时还能保持光滑区域的精度。
A simple WENO limiter is applied to an h-adaptive RKDG algorithm based on troubled-cell indicators,and the resulting algorithm is numerically proved that it can improve the solution quality near the discontinuities.The numerical tests also indicate that the simple WENO limiter can produce oscillation-free solutions when one-dimensional h-adaptive mesh is used,and can still maintain the accuracy on smooth regions.
