A one dimensional hydrodynamic simulation of colliding quasi neutral plasma systems
… a flux-corrected transport algorithm with an Eulerian grid in order to solve the three Euler equations for hydrodynamic flow. It includes source terms appropriate for high-density, high-temperature plasmas, such as those produced on dense targets at the focus of intense laser beams. Stagnation …

A blurred interface formulation of The Reference Map Technique for Fluid-Solid Interactions and Fluid-Solid-Solid Interactions
… large deformations all performed on a single Eulerian grid with no Lagrangian particles whatsoever. The Reference Map Technique (RMT) provides an Eulerian simulation framework allowing to compute fully coupled fluid/soft-solid interactions. However, due to the extrapolations inherent to the …

Computation of moving interface flows in biophysical applications
… technique, the fluid equations are solved in an Eulerian grid and the structure is treated as a network of Lagrangian nodes. The communication between the fluid and structure dynamics is established by the use of the Dirac delta function. Utilizing the immersed boundary method, we have studied …

Comparison of Two Vortex-in-cell Schemes Implemented to a Three-dimensional Temporal Mixing Layer
… and the computational domain is covered by Eulerian mesh. Velocity field is computed on the mesh by solving Poisson equation. The solution proceeds in time by advecting the particles with the flow. Second order Adam-Bashford method is used for time integration. Exchange of information …

Finite Element Simulation of Interfacial Flows on Unstructured Meshes using a Second-order Accurate VOF Method
… derivative is used for the flow field on a fixed Eulerian grid. This approach enables us, in particular, to implement equal-order interpolation for the velocity and pressure. Streamline upwind Petrov-Galerkin (SUPG) stabilization is used for convection-dominated flows. Fluid interfaces are …

Application of pressure-projection algorithms to a sharp projection immersed boundary method for the incompressible Navier-Stokes equations
… This method seems applicable to any grid system and was widely accepted due to its ease of use and straightforward derivation of the order of accuracy for the pressure. It rendered another class of projection methods which relied on global pressure-updating hopeless as Strikwerda and …

Modelling surface evolution coupled with tectonics
This study presents the development of 1D and 2D Surface Evolution Codes (SECs) and their coupling to any lithospheric-scale (thermo-)mechanical code with a quadrilateral structured surface mesh. Both SECs involve diffusion as approach for hillslope processes and the stream power law to reflect …
