The user’s spacecraft class example is then thermally analyzed by calculating radiation conductors (Radk), calculating external heating rates (Heatrate) from the Sun and Earth from a defined orbit (Orbit), and calculating a conduction and capacitance network (CONCAP). The calculated inputs are then combined to produce a thermal math model and run in a finite-difference solver, SindaWin. The results are presented as temperature versus time plots (XYPlot) and mapping the temperature data onto the 3D model (Geometry).
