Effects of radiogenic heat production and mantle compressibility on the behaviors of Venus’ and Earth’s mantle and lithosphere

Benchmarking multiphysics software for mantle convection

“…However, there are still several other facets that should be tested in the future. For example, compressible convection is an option within the laminar flow physics module (following the work of Lee (2014)). Thermochemical convection should also be tested using the level set and phase field methods.…”

“…Accordingly, COMSOL® is also a viable option for introducing students to geodynamic modeling. COMSOL® has been utilized in the geosciences (Azad et al, 2016;Bird et al, 2014;Butler and Sinha, 2012;Butler and Zhang, 2016;Halloran et al, 2019;Li and Smith, 2015;Nardi et al, 2014;Pirnia et al, 2019), including mantle convection studies (Herein and Galsa, 2011;Lee, 2014;Lee and Wada, 2017;Shahraki and Schmeling, 2012;Sinha and Butler, 2009;Shiels and Butler, 2015). However, it appears the software has not been benchmarked in detail for mantle convection problems.…”
