Grain Design Program Lite

Grain Design Program Lite (GDP) is capable of calculating all 2D-grains, like stars, moonburners, slotted grains, and BATES grains. Geometries are devided into four categories as simple stars are treated analytically, simple cylinders (like BATES), treated analytically, and aAll other shapes are calculated graphically. The user provides a file (.pcx, .gif, or .bmp) of the grain. GDP automatically finds burning areas and calculates burnback. This options allows full burn-back, including slivers. Even cracks can easily be drawn with a drawing program, and modeled. Tabular input allows grain input by entering burning area and burning volume as function of burn depth.
