Figure 1A classic experiment to show thermal equilibration is to put a small Petri dish filled with some hot or cold water into a larger one filled with tap water around room temperature, as illustrated in Figure 1. Then stick one thermometer in the in…
Copyright: ACS Nano, American Chemical SocietySelf-assembled peptide nanostructures have unique properties that lead to applications in electrical devices and functional molecular recognition. Exactly how to control the self-assembly process in a solut…
Download the models Although it is mostly used as an engineering tool, our Energy2D software can also be used to create simple Earth science simulations. This blog post shows some interesting results about the Hadley Cell. The Hadley Cell is an atmospheric circulation that transports energy and moisture from the equator to higher latitudes in […]
Fig. 1: IR image of a wall junction (inside) by Stefan Mayer One of the mysterious things that causes people to scratch their heads when they see an infrared picture of a room is that the junctions such as edges and corners formed by two exterior walls (or floors and roofs) often appear to be […]
In Version 2.3 of Energy2D, I have added full support of undo/redo for most actions. With this feature, you can undo all the way back to your starting point and redo all the way forward to your latest state. This is not only a must-have feature for a d…
Many users asked if there is any good tutorial of Energy2D. I apologize for the lack of a User Manual and other tutorial materials (I am just too busy to set aside time for writing up some good documentations).So Carmen Trudell, an architect who curren…
Computational fluid dynamics (CFD) is an important research method that uses numerical algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and…
In the year 2014, Energy2Dhas incorporated a radiation simulation engine and a particle simulation engine, expanding its modeling capacity and making it a truly multiphysics simulation package. To celebrate the New Year, I made some simulations that…
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…
