The following files pertain to the fortran code displayed. The goal was to model a 3-Dimensional interaction between two Argon atoms, and make a movie of it. The included movie requires a Quicktime player to be viewed. If you don't have one, you can click here.
The link above leads to the source code for a 3-D interaction between two Argon atoms at an initial radius of 3.44 Angstroms. The Lennard-Jones force and potential determine the physics behind the interaction. It has a net total energy conservation, with minimal fluctuation. It uses Argon's L-J constant values. It uses a timestep of 10^-15, and the loop goes for 10,000 iterations, for a total of 3 bounces. The Excel spreadsheet, below, has all of the data concerning Radius, Force and Total Energy.
The above link leads to the exact file that VMD read to produce the quicktime movie. The file is in XYZ molecular format.
The above link leads to the movie file, in quicktime format. It was created using VMD software, which is free to download from the University of Illinois, where it was developed. Its excellent software, and has an excellent mailing list and user base. I hope you enjoy the show.
Thanks to all of the very hard working individuals at the Beckman Institute who helped make my life a lot easier while making the movie file.
