Virtual Environment interfaces are designed by implementing an interaction metaphor and comparing it to existing implementations. This technique has proven effective in desktop interfaces but the difficulty of working inside a VE remains because VE interfaces do not understand what the user is trying to do, only what the metaphor wants to do. To handle this problem, we investigated a lower-leve...

We propose a practical numerical framework for free surface flows with surface tension force. The numerical framework consists of the CLSVOF (coupled level set and volumeof-fluid) method, the THINC/WLIC (tangent of hyperbola for interface capturing/weighted line interface calculation) scheme, multi-moment methods (CIP-CSL and VSIAM3) and the density-scaled CSF (continuum surface force) model. W...

We present a discrete exterior calculus (DEC) based discretization scheme for incompressible two-phase flows. Our physically-compatible of single phase flow is extended to simulate immiscible flows with discontinuous changes in fluid properties such as density and viscosity across the interface. The Navier-Stokes equations conservative field equation interface capturing are first transformed in...

Abstract The grain envelope model (GEM) describes the growth of envelopes dendritic crystal grains during solidification. Numerically growing are usually tracked using an interface capturing method employing a phase field equation on fixed grid. Such approach as diffuse interface, which can lead to numerical artefacts that possibly detrimental. In this work, we present sharp-interface formulati...

We present a novel interface-capturing scheme, THINC-scaling, to unify the VOF (volume of fluid) and level set methods, which have been developed as two different approaches widely used in various applications. The key success is maintain high-quality THINC reconstruction function using field accurately retrieve geometrical information fulfill numerical conservativeness. interface well defined ...
