Abstract
We have developed a visualization software for molecular dynamics (MD) simulation program MXDORTO under "object oriented program." We have named it "Visualizer for Molecular Dynamics Simulation (MDVIS)." The each atom position calculated by MD program is displayed continuously in main form. Inter atomic bonds and the trajectory of each atom can be shown in main form, too. The result of simulation such as temperature, pressure, density, molar volume, cell parameters and internal energy is plotted versus simulation time in chart form.
