Interactive science (Image credit: Franco Landriscina)If future historians were to write a book about the most important contributions of technology to improving science education, it would be hard for them to skip computer modeling and simulation.Much…
SimBuilding (alpha version) is a 3D simulation game that we are developing to provide a more accessible and fun way to teach building science. A good reason that we are working on this game is because we want to teach building science concepts and prac…
An array of heliostats in Energy2D (online simulation)A new class of objects was added in Energy2D to model what is called a heliostat, a device that can automatically turn a mirror to reflect sunlight to a target no matter where the sun is in the sky….
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…
Figure 1. A stock-and-flow model of building energy. Our Energy3D CAD software has two built-in simulation engines for performing solar energy analysis and building thermal analysis. I have extensively blogged about solar energy analysis using Energy3D. This article introduces building thermal analysis with Energy3D. Figure 2. A colonial house. The current version of the building […]
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…
The National Science Foundation and the Popular Science Magazine have announced that “Beautiful Chemistry” won the Expert’s Choice Award for Video at the 2015 Visualization Challenge, known as Vizzies. According to the Popular Science Magazine, For many, the phrase “chemical reactions” conjures memories of tedious laboratory work and equations scribbled on exams. But Yan Liang, […]
Figure 1With the releases of two competitively priced IR cameras for smartphones, the year 2014 has become a milestone for IR imaging. Early in 2014, FLIR unveiled the $349 FLIR ONE, the first IR camera that can be attached to an iPhone. Months later, …
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…
