The development of a Cartesian cut cell method for incompressible viscous flows
International Journal for Numerical Methods in Fluids, 2006AbstractThis paper describes the extension of the Cartesian cut cell method to applications involving unsteady incompressible viscous fluid flow. The underlying scheme is based on the solution of the full Navier–Stokes equations for a variable density fluid system using the artificial compressibility technique together with a Jameson‐type dual time ...

An extended cut-cell method for sub-grid liquids tracking with surface tension
ACM Transactions on Graphics, 2020Simulating liquid phenomena utilizing Eulerian frameworks is challenging, since highly energetic flows often induce severe topological changes, creating thin and complex liquid surfaces. Thus, capturing structures that are small relative to the grid size become intractable, since continually increasing the resolution will scale sub-optimally due to the

A Cut Cell Discontinuous Galerkin Method for Particulate Flows
2019Heutzutage sind zahlreiche Phänomene von Partikelströmungen noch immer nicht vollständig verstanden. Dazu trägt ein Mangel von hochgenauen und effizienten Lösern bei, speziell für Partikel mit beliebiger Gemoetrie. Das diskontinuierliche Galerkin-Verfahren ermöglicht durch seine hohe Konvergenzordnung sowohl höchste Genauigkeit als auch effiziente ...

A cut‐cell non‐conforming Cartesian mesh method for compressible and incompressible flow
International Journal for Numerical Methods in Engineering, 2007AbstractThis paper details a multigrid‐accelerated cut‐cell non‐conforming Cartesian mesh methodology for the modelling of inviscid compressible and incompressible flow. This is done via a single equation set that describes sub‐, trans‐, and supersonic flows.

Advances in Applied Mathematics and Mechanics, 2017
Summary: A new sharp interface method with the combination of Ghost Fluid Method (GFM) and Cut Cell scheme is developed to study compressible multi-phase flows with clear interfaces. Straight-line cutting is applied on the cells passed by the interface. A new real-ghost mixing method is presented and applied around the cut cells to deal with very small

A robust cut-cell method for fluid-structure interaction on adaptive meshes
21st AIAA Computational Fluid Dynamics Conference, 2013A new cut-cell method to simulate the interaction of a viscous fluid with rigid boundaries is presented. The method is based on a strictly conservative Cartesian cut-cell scheme and accounts accurately for the fluid forces exerted on the solid boundaries.

A robust cut‐cell finite element method for Poisson's equation in three dimensions
International Journal for Numerical Methods in EngineeringSummaryThis article documents a cut‐cell finite element method for solving Poisson's equation in smooth three‐dimensional domains using a uniform, Cartesian axis‐aligned grid. Neumann boundary conditions are imposed weakly by way of a Delaunay triangulation, while Dirichlet boundary conditions are imposed strongly using a projection method.
