Well, I figured it out myself last night. http://molecularworkbench.blogspot.com/2010/09/mystery-solved.html

Hi all: I have been puzzled by a very simple experiment I did lately. I found there exists a temperature gradient in a cup of saturated salt water--the bottom is about 0.5 Celsius warmer than the top. That is after the solution has been left intact for more than 100 hours. There is no such...

You can visit http://mw.concord.org and download the Molecular Workbench software (using the third button on that page) to your disk and double-click on the mw.jar file. It will launch the application. Then you can explore within it.

Hi: I am working on a quantum dynamics simulator that can perhaps be used to learn quantum mechanics without resorting to the formalism. This approach may have a great potential. Here are some links to some results: 1. http://mw.concord.org/modeler1.3/mirror/quantum/coulomb.html...

From what you described, I cannot tell whether the energy in your simulation is conserved or not. The total energy (i.e. p.e. plus k.e.) should conserve nearly perfectly if you use a smoothing function to avoid the error caused by the potential cutoff. A classical book for learning MD...

The Molecular Workbench software I think the Molecular Workbench may be what you are looking for. The software provides a virtual lab environment in which you can create molecular dynamics models and run them immediately. The whole simulation environment is embedded in a word processor that...

Concord Consortium, an educational non-profit, offers a free simulation program called Molecular Workbench, which can be used to learn physics, chemistry and biology through cool simulations. The main page to download the software is: http://workbench.concord.org/modeler/index.html...
