The MIT website carry’s a software package created by Geoffrey Forden of Arms Control Wonk that can simulate ballistic missile flight.
With the current flurry of ballistic missile tests someone may find the software useful.
A description of the simulation software follows:
GUI_Missile_Flyout is a stand-alone program running under Windows for simulating ballistic missiles with 1, 2, or 3 stages in a framework with a round, rotating Earth. Users can easily input all the necessary parameters in an intuitive graphical user interface (GUI). A modest number of quantities can be interactively plotted on the Interface but the complete trajectory can be saved as either an Excel or Matlab file for further analysis. The trajectory can also be directly displayed in Google Earth for visualization. The GUI can be used to optimize gravity turn parameters to maximize range or aim at a specific target (entered, as is the launch site) through latitude-longitude pairs. In addition to an introduction to using the program, this paper describes the integration of the three-degrees-of-freedom equations of motion and approximations made to the aerodynamic (such as a parameterized drag coefficient, Cd). ……………………
