I think you missed my point. Please re-read with emphasis
on my reaction to your phrase "different than the expected result".
Keyword: "expected"

Correct me if I'm wrong, but it seemed to me
that you were advocating this cycle:
1.) run a simulation of a physical system
2.) if the simulation produces results *contrary to expectation*,
"educate" the simulation program to produce _expected_
3.) goto #1

You then respond with what seems a partial modification -
feed real world results back into the simulation... OK, but
what does the follow-on utterance about domain specificity have to do
with anything? We weren't talking about that.
