Thermodynamica
thermodynamica is a library mod for adding realistic heat transfer to minecraft.
About this Mod
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!

Server lagging with Thermodynamica – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Thermodynamica consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
