抽象。地球动力学模型为研究地壳、地幔和地核中不可直接观测的过程提供了一个强有力的工具。然而，数值模型固有地受制于它们所基于的假设和简化。为了适当地使用和审查数值模拟研究，人们需要了解地球动力学模型的局限性及其优点。在这里，我们提出了一个全面而简洁的概述适用于固体地球的地球动力学建模过程中，从控制方程的选择，数值方法，模型设置，模型解释，并最终通信的模型结果。我们强调最佳实践并讨论其实现，包括代码验证，模型验证，内部一致性检查以及软件和数据管理。因此，从这个角度来看，我们鼓励高质量的建模研究，公平的外部解释，并合理使用已发表的作品。我们提供了大量的例子，从岩石圈和地幔动力学，特别是，并指出与相关领域，如地震学，构造物理学，地质学，矿物物理学，行星科学和大地测量学的协同作用。我们澄清和巩固地球动力学和数值建模的术语，为建模研究的清晰沟通制定标准。总之，本文介绍了地球动力学建模的基础知识，供来自不同背景的首次和经验丰富的建模者、合作者和评审者使用，以（重新）全面了解地球动力学建模。
Abstract. Geodynamic modelling provides a powerful tool to investigate processes in the Earth's crust, mantle, and core that are not directly observable. However, numerical models are inherently subject to the assumptions and simplifications on which they are based. In order to use and review numerical modelling studies appropriately, one needs to be aware of the limitations of geodynamic modelling as well as its advantages. Here, we present a comprehensive yet concise overview of the geodynamic modelling process applied to the solid Earth from the choice of governing equations to numerical methods, model setup, model interpretation, and the eventual communication of the model results. We highlight best practices and discuss their implementations including code verification, model validation, internal consistency checks, and software and data management. Thus, with this perspective, we encourage high-quality modelling studies, fair external interpretation, and sensible use of published work. We provide ample examples, from lithosphere and mantle dynamics specifically, and point out synergies with related fields such as seismology, tectonophysics, geology, mineral physics, planetary science, and geodesy. We clarify and consolidate terminology across geodynamics and numerical modelling to set a standard for clear communication of modelling studies. All in all, this paper presents the basics of geodynamic modelling for first-time and experienced modellers, collaborators, and reviewers from diverse backgrounds to (re)gain a solid understanding of geodynamic modelling as a whole.
