Unconditionally stable solvers for time-dependent ordinary or partial differential equations are desirable in game development because they are highly resilient to player actions — they never “blow up.” In the entertainment industry, unconditionally stable solvers for creating visual fluid effects (e.g., flow, smoke, or fire) in games and movies were popularized by Jos Stam’s 1999 […]
Two recently published Springer books have featured our visual simulation software, indicating perhaps that their broader impacts beyond their originally intended audiences (earlier I have blogged about the publication of the first scientific paper tha…
The November issue of the Remote Sensing of Environment published a research article “Magma emission rates from shallow submarine eruptions using airborne thermal imaging” by a team of Spanish scientists in collaboration with Italian and American scientists. The researchers used airborne infrared cameras to monitor the 2011–2012 submarine volcanic eruption at El Hierro, Canary Islands […]
Fig. 1: Particle advection behind two obstacles.Advection is a transport mechanism in which a substance is carried by the flow of a fluid. An example is the transport of sand in a river or pollen in the air. Advection is different from diffusion, where…
Fig. 1: Swirling flows form between two opposite fans.A new type of object, “fan”, has been added to Energy2D to create and control fluid flows. This fan replaces the original implementation of fan that assigns a velocity to a solid part (which doesn’t…
Figure 1: Moving sensors facing a rectangular radiator.The heat flux sensor in Energy2D can be used to measure radiative heat flux, as well as conductive and convective heat fluxes. Radiative heat flux depends on not only the temperature of the object …
Figure 1. Mechano-thermal simulation of inelastic collision.Many existing simulations of inelastic collisions show the changes of speeds and energy of the colliding objects without showing what happens to the lost energy, which is often converted into …
Figure 1: Stefan’s Law in action.The original ray-tracing radiation solver in our Energy2D software suffers from performance problems as well as inaccuracies (no, light particles do not travel that slowly as shown in it). After some sleepless nights, I…
Figure 1: A demo simulation.A heating element converts electricity into heat through Joule heating: Electric current passing through the element encounters resistance, causing the temperature of the element to rise. A thermistor is a type of resistor w…
Figure 1: Particle motions driven by convective flow.Up to yesterday, our Energy2D software has been a program for simulating, mostly, fluid and heat flows. But there are also objects in the world that are not fluids. To simulate that part of the world…
