Question: You run a simulator twice with exactly the same input, but the output of the two runs is slightly different. For example, a water mole

You run a simulator twice with exactly the same input, but the output of the two runs is slightly different. For example, a water mole fraction is reported as $0.98014 \mathrm{E}-02$ and as $0.98011 \mathrm{E}-02$, and a product flow rate is reported as 5780.723 and as $5780.716 \mathrm{~kg} / \mathrm{h}$. (These are real values from Lab 8, Part II.) Should you be concerned? Why are the numbers different?
