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…
Figure 1. Global insolation pattern from Pole to PoleThe Sun’s power drives the climate of the Earth. Accurately modeling the incident solar radiation, namely, insolation, at a given location is important to the design of high-performance buildings. As…
The Nobel Prize winner Doris Lessing, author of more than 50 books, had a rare talent for writing in different styles about a variety of people, from adolescent boys, to lonely old women, to kings and queens living on another planet. She had a brilliant novelist’s intuitive understanding of other people’s minds. In her slender […]
Figure 1 As it travels through the atmosphere of the Earth, the light from the Sun interacts with the molecules in the air and are scattered or absorbed, causing the radiation energy that ultimately reaches the ground to weaken. This effect is more significant in early morning or late afternoon than at noon because sunlight […]
A Molecular Workbench virtual experiment used in the Iranian study.In the May Issue of Journal of Educational and Social Research, published by MCSER (Mediterranean Center of Social and Educational Research) in Rome, researchers from Iran and Malaysia …
Figure 1 (go to simulation)There have been some confusions lately about the heat transfer representations in Energy2D simulations. By default, Energy2D shows the temperature distribution and uses the change of the distribution to visualize heat flow. T…
Add any number of sensors to a house.According to Wikipedia, computer-aided engineering (CAE) is typically done through the following steps:Pre-processing: This step defines the 3D geometry, the initial conditions, and the boundary conditions of the mo…
Two international students will spend the summer coding for our open source projects. Through Google Summer of Code™ (GSoC), they’ll earn stipends from Google, plus get a coveted GSoC t-shirt and certificate. Concord Consortium developers will provide mentorship.
Many people know that south-facing windows can help to heat a house in the winter because they let a lot of sunlight in. Exactly how much of the south-facing wall should we allocate to windows? What are the downsides? How can we avoid them? Our Energy3D software allows students to explore the problems and find […]
Energy3D (Tree image credit: SketchUp Warehouse and Ethan McElroy)A zero-energy building is a building with zero net energy consumption over a year. In other words, the total amount of energy used by the building on an annual basis is equal to or even …
