Screenshots, known for years as capturing Graphical User Interface by means of print screen button or capturing software, is not only beneficial for creating user guide or user manual document, but also for reverse engineering process. This paper presents a new way of capturing the data appear on a screen by creating the ontology of its interface. Data capturing based on the interaction style o...

A preconditioned five-equation two-phase model coupled with an interface sharpening technique is introduced for simulation of a wide range of multiphase flows with both high and low Mach regimes. Harten-Lax-van Leer-Contact (HLLC) Riemann solver is implemented for solving the discretized equations while tangent of hyperbola for interface capturing (THINC) interface sharpening method is applied ...

We provide an overview of the finite element methods we developed in recent years for computation of fluid dynamics problems with moving boundaries and interfaces. This class of problems include those with free surfaces, two-fluid interfaces, fluid–object and fluid–structure interactions, and moving mechanical components. The methods developed can be classified into two main categories: interfa...

When using high-order accurate shock-capturing methods, e.g., weighted essentially non-oscillatory schemes (WENO), numerical errors are often generated in simulations of isolated contact discontinuities and material interfaces when trying to capture these features on a grid. Spurious pressure oscillations are generated at interfaces and contacts propagate through the flow field. In addition, te...
