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
