I also think that I ask for a lot. And I know that simulation is hard, error-prone, and often more expensive than just buillding the real system. However, building the system does not always give the insight that a simulation can give, and it's sometimes prohibitively expensive. More specifically, I already had built the system, but I couldn't get the information out of it without disturbing it too much. That's why I wanted to simulate it.
