The plain-English version
The interval by which a numerical simulation advances its represented time.
Why it matters
Its size influences accuracy, stability, and computational cost.
Let’s make it click
A model updates a virtual temperature process at defined intervals.
Vibe Bro’s heads-up
A smaller step is not a universal proof of correctness; check convergence and whether the chosen integration method fits the model.

Supported: Time step influences cost, accuracy, and stability, with convergence/method suitability rather than smaller-is-always-correct claims.
