This is engineering development at its finest. Simulation only gets you so far. SpaceX is working an incredibly complicated problem. Weight versus fuel and thrust. The materials are also a serious complication as the temperature of outer space is extremely variable from cryogenic to hot (the unfiltered Sun shining on parts). Lynn
