Planetary Geodynamic Model Collection of Open Source Software, Teaching Materials and Benchmarks

To investigate the interior structure, dynamics and evolution of terrestrial planets, numerical models have become an essential tool for many researchers. Modelers often struggle with outreach and accessibility, especially when aimed towards students and scientists in an interdisciplinary field. We are therefore constructing a collection of several codes of varying complexity in planetary geodynamics developed in our work group.

Firstly, we present an updated Version of the code CHIC, which is a collection of applications, spanning 1D parameterized interior structure and thermal-evolution models to 2D (for some applications up to 3D) thermo-chemical convection models. The code will now be published under an open-source software license. The release will include an updated documentation of the code.

Furthermore, we will release multiple shorter Python codes, mainly as teaching material. These will include models of:

- Tidal heat dissipation, for variable planetary systems.

- Interior structure in 1D, based on the planet’s properties.

- Thermal evolution in 1D, based on interior structure and tectonic regime.

- Simplified 2D thermal convection with temperature- and pressure-dependent viscosity.

Instructions on installation, application and evaluation are presented in short tutorials. The goal is to create a framework for our work group to publish software related to modeling of planetary interiors. The demographic includes students, teachers and scientists, as the codes range from educational material to advanced scientific models.

We also provide several educational examples and showcases of common benchmarks. In addition, we will present a new benchmark that we are currently developing for the reconstruction of convection patterns from combined grain flow and fluid flow experiments.
