Planetary Thermal Evolution Simulator

Description

PlanetaryHeatSim is a full-featured one-dimensional planetary thermal evolution simulator built around the spherical heat diffusion equation, layered material models, radiogenic heating, and convection parameterizations. The project combines a flexible numerical backend with a modern desktop GUI, making it possible to move from physical model definition to simulation and visualization in a single environment.

What makes the project especially strong is its combination of physics configurability and numerical breadth. The code supports multiple classes of explicit and implicit ODE solvers, rich YAML-based configuration of planetary structure and constitutive laws, and a comprehensive visualization and export pipeline. Rather than being just a teaching demo, it functions as a compact research-oriented platform for experimenting with thermal evolution scenarios across planetary bodies such as Earth, Mars, the Moon, and Io.

  • Implemented a 1D spherical thermal evolution model with layered material properties, radiogenic heating, and convection parameterizations.
  • Added a broad solver suite including explicit RK, Adams methods, BDF, IRK, and SDIRK families.
  • Built a modern GUI for YAML editing, simulation control, progress tracking, and interactive result browsing.
  • Created a full results pipeline with automatic plots, exports, and parallelized temperature-profile visualization.
  • Packaged preset planetary configurations for Earth, Mars, Moon, and Io to support comparative thermal studies.
