A Navier-Stokes Solver for Compressible Turbulent Flows on Quadtree and Octree Based Cartesian Grids
Journal of Applied Fluid Mechanics, 2019 Cartesian grids represent a special extent in unstructured grid literature. They employ chiefly created algorithms to produce automatic meshing while simulating flows around complex geometries without considering shape of the bodies.

Recent Advances in Cartesian-Grid DFT in Atoms and Molecules
Frontiers in Chemistry, 2022 In the past several decades, density functional theory (DFT) has evolved as a leading player across a dazzling variety of fields, from organic chemistry to condensed matter physics. The simple conceptual framework and computational elegance are the underlying driver for this. This article reviews some of the recent developments that have taken place in

Immersed Boundary Method Using Ghost Cells in a Three-Dimensional Case
Современные информационные технологии и IT-образование, 2020 When solving numerically gas dynamics problems, one often encounters difficulties in processing regions with complex geometry. Generating consistent computational grids for such areas may be a complex task.

Graphs and Combinatorics, 2020 Graph burning is a discrete-time process on graphs, where vertices are sequentially burned, and burned vertices cause their neighbours to burn over time. We consider extremal properties of this process in the new setting where the underlying graph is also changing at each time-step.

A simple Cartesian scheme for compressible multimaterials [PDF]
, 2014 We present a simple numerical method to simulate the interaction of two non-miscible compressible materials separated by an interface. The media considered may have significantly different physical properties and constitutive laws, describing for example

Advanced Materials Technologies, EarlyView.A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Conditions for isonemal arrays on a Cartesian grid
Linear Algebra and its Applications, 1984 AbstractThe concept of an isonemal binary array on a Cartesian grid is examined, and rules for constructing all such arrays are identified. Examples are included for the various possible constructions, and tables of compound twillins of periods six and eight are given.

Stability of the DuFort–Frankel Scheme on Unstructured Grids
ComputationThe DuFort–Frankel scheme was introduced in the 1950s to solve parabolic equations, and has been widely used ever since due to its stability and explicit nature. However, for over seven decades, its application has been limited to Cartesian grids.

Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...
