The plain-English version
Verification checks that code implements the intended model; validation checks whether the model is adequate for its intended use.
Why it matters
It prevents successful execution from being mistaken for real-world accuracy.
Let’s make it click
Compare a solver with an analytic toy case, then compare the model with relevant observations.
Vibe Bro’s heads-up
A model can be implemented correctly and still omit important effects, use poor parameters, or be applied outside its useful range.
