Hi:

I would like to share Energy2D: [url=http://energy.concord.org/energy2d/index.html]http://energy.concord.org/energy2d/index.html[/url]

This is a Java-based online computational fluid dynamics applet and application that allows you to study thermodynamics and heat transfer at the macroscopic level.

We found many students love our convection simulations:
