By introducing temperature-based viscosity, you can vary how your fluid behaves across the simulation.

Hotter areas → more fluid and energetic
Cooler areas → thicker and more resistant

This gives you much more control over motion:
• Sharper or softer splashes
• Controlled energy dissipation
• Better contrast between calm and turbulent regions

It’s a simple change, but it can completely shift how believable and art-directable your sims feel.
