Orbital-free density functional theory using higher-order finite differences
… We present a real-space formulation and higher-order finite-difference implementation of periodic Orbital-free Density Functional Theory (OF-DFT). Specifically, utilizing a local reformulation of the electrostatic and kernel terms, we develop a generalized framework suitable for …

Shallow water equations in real-time computer graphics
… are used, they are usually achieved using low order numerical methods resulting in the need for unphysical post-processing of the results. In order to avoid resorting to such ad-hoc solutions, a new numerical method based on higher order finite differences was developed. This new method was …
