“…Hybrid methods have been proposed to model both macroscopic and microscopic fluid phenomena in one scene. Irving et al [2006] coupled 2D and 3D simulation techniques to model large quantities of water with surface details. Nobile [2009] proposed a two-way coupled method to simulate blood flow at various resolutions and tested the system using a very simplified model.…”

This paper presents a lightweight sketching system that enables interactive illustration of complex fluid systems. Users can sketch on a 2.5-dimensional (2.5D) canvas to design the shapes and connections of a fluid circuit. These input sketches are automatically analyzed and abstracted into a hydraulic graph, and a new hybrid fluid model is used in the background to enhance the illustrations. The system provides rich simple operations for users to edit the fluid system incrementally, and the new internal flow patterns can be simulated in real time. Our system is used to illustrate various fluid systems in medicine, biology, and engineering. We asked professional medical doctors to try our system and obtained positive feedback from them.

“…Although the simplest schemes trace back along straight line characteristics and use low order interpolation to estimate the data, one can trace back arbitrarily high order curved characteristics and use arbitrarily high order interpolation, see for example [38]. The simplicity of these schemes makes them quite useful for adaptive grids and other data structures, see for example [7,31,30,47,16]. Recently, authors have considered using semi-Lagrangian methods as building blocks in other schemes, for example [17,18,6] showed that the second order accurate BFECC method of [5] can be made unconditionally stable using the first order accurate semiLagrangian method as a building block.…”

Semi-Lagrangian methods have been around for some time, dating back at least to [3]. Researchers have worked to increase their accuracy, and these schemes have gained newfound interest with the recent widespread use of adaptive grids where the CFL-based time step restriction of the smallest cell can be overwhelming. Since these schemes are based on characteristic tracing and interpolation, they do not readily lend themselves to a fully conservative implementation. However, we propose a novel technique that applies a conservative limiter to the typical semi-Lagrangian interpolation step in order to guarantee that the amount of the conservative quantity does not increase during this advection. In addition, we propose a new second step that forward advects any of the conserved quantity that was not accounted for in the typical semi-Lagrangian advection. We show that this new scheme can be used to conserve both mass and momentum for incompressible flows. For incompressible flows, we further explore properly conserving kinetic energy during the advection step, but note that the divergence free projection results in a velocity field which is inconsistent with conservation of kinetic energy (even for inviscid flows where it should be conserved). For compressible flows, we rely on a recently proposed splitting technique that eliminates the acoustic CFL time step restriction via an incompressible-style pressure solve. Then our new method can be applied to conservatively advect mass, momentum and total energy in order to exactly conserve these quantities, and remove the remaining time step restriction based on fluid velocity that the original scheme still had.

“…In particular, many methods have been developed to visualize fluids realistically simulations; however, the computational cost of these methods have always been high [1] [2]. With the recent developments of techniques for obtaining faster simulations using high performance-computers, it has now become possible to calculate fluid simulations in real time.…”

Virtual Noctiluca: Interaction between Light and Water Using Real-Time Fluid Simulation and 3D Motion Measurement

Abstract. In recent years, with the rapid improvement of the performance of computers, new possibilities for real-time simulation technologies are emerging. In this study, we simulated the behavior of water in real time and combined this simulation with a measurement of the user's 3D motion to simulate the interaction between water and light, as observed in Noctiluca. Noctiluca is oceanic plankton that produces light when physically stimulated. Stirring the surface of water containing Noctiluca in a completely dark place causes the surface to glow, and an observer can gain the mystical and fantastic experience of watching the glow becoming dim with the flow of the water.
