Thermodynamica is a high-performance heat simulation engine for Minecraft. It handles complex temperature diffusion using a parallelized Breadth-First Search algorithm, ensuring that even thousands of active heat sources won't choke your server.

Features:

Multi-Threaded: Simulation runs in parallel to the main tick to preserve performance.
Full Customization: Define any block as a heat source or an insulator.
Material Physics: Wool insulates, metals conduct, and air dissipates.
API-First: Built to be used as a backend for other mods requiring realistic temperature data.

Getting Started

This mod is a "naked" engine. To see heat in action, you need to add thermal Data Packs to your world. We provide ready-to-use packs for:
Minecraft Vanilla
Create Mod

Modder-Friendly
We've included a standalone Python GUI tool in the github repo to let you generate custom Data Packs without writing a single line of JSON. Just name the block, slide the bars, and hit save!
