Mathematical and Computational Applications, Volume 26, Issue 4

2021 December - 17 articles

Cover Story: In long-time simulations of hyperbolic conservation laws, it seems to be very different and extremely challenging to achieve considerably high resolutions and meanwhile avoid spurious oscillations by most existing WENO schemes. During the last decade, this issue has attracted considerable scholarly interest but the way of completely addressing it has remained unclear up to now. We develop the novel concept of order-preserving (OP) mapping, and the resultant WENO schemes can successfully fix the aforementioned problem. These schemes also have many other merits even in short-time simulations, such as improving the resolutions in the high-frequency smooth wave regions, significantly reducing the post-shock numerical oscillations of two-dimensional problems with shock waves, as well as greatly limiting the numerical oscillations in the framework of component-wise reconstruction. View this paper.

Modeling the Spread of COVID-19 in Enclosed Spaces

  • Matthew David Gaddis and
