VMD stands for Visual Molecular Dynamics. It is used for molecular modeling and visualization for displaying, animating, and analyzing large biomolecular systems using 3-D graphics and built-in scripting.
VMD is primarily developed as a tool for viewing and analyzing the results of molecular dynamics simulations, but it also includes tools for working with volumetric data, sequence data, and arbitrary graphics objects.
