Description

Thermodynamica: High-Performance Multi-Threaded Heat Simulation
Thermodynamica is a robust, library-style mod designed to bring realistic temperature mechanics to Minecraft without the lag. It implements a sophisticated Parallel BFS (Breadth-First Search) Engine that calculates temperature diffusion across your world on separate threads, keeping your server TPS smooth even with complex thermal setups.
The "Naked" Simulation
Thermodynamica is designed as a simulation framework. Out of the box, it provides the "physics" but leaves the block definitions to you.
Note: You must install a compatible Data Pack to define your heat sources and material properties. There are 2 official datapacks:
Vanilla and create


Key Features

Threaded Performance: Heat spreading is calculated independently of the main game loop meaning low thermal TPS wont affect game TPS.
Dynamic Materials: Every block can have custom Conductivity (how fast heat moves), Transfer Rate, and Dissipation (loss to the environment).
Data Pack Driven: 100% of the block data is hot-reloadable via standard Minecraft JSONs. No Java knowledge required.
Ambient Awareness: Temperatures naturally re-equilibrate based on the biome's ambient temperature.
Easy Tooling
Included in the mods github repo is a Python-based GUI Tool (thermal_tool.py) that lets you:
Enter any block registry name.
Use visual sliders to tune thermal values.
Instantly generate or update Data Packs with a single click.
Commands
/thermodynamica status - Check active heat sources and engine health.
/thermodynamica tps - View detailed simulation profiling.

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!
