internal ballistics simulator for rocket motor experimenters

Description

openMotor is an open-source internal ballistics simulator for rocket motor experimenters. The software produces estimates of a rocket motor's chamber pressure and thrust based on input such as propellant properties and grain geometry. It uses the Fast Marching Method to determine how a propellant grain regresses, which allows the use of arbitrary core geometries.

Current Features:
  * Metric and imperial units
  * Support for common grain geometries such as BATES, Finocyl, Star and more
  * Loading custom grain geometry from DXF files
  * A propellant editor that allows the user to enter the properties of as
    many propellants as they wish
  * The grain editor displays how a grain will regress to cut down on the
    guesswork involved in tweaking geometry
  * ENG file exporting
  * Burnsim importing and exporting
  * A UI that supports saving and loading designs along with undo and redo.

Planned Features:
  * Erosivity simulation
  * Detailed output of every calculated parameter at any time and position
    along the motor
