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…
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…
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…
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 …
