Model Archive for Paper: "Tectonism and Enhanced Cryovolcanic Potential Around a Loaded Sputnik Planitia Basin, Pluto"

Abstract

This archive contains files used to create and plot results from the spherical shell loading models presented in the paper McGovern, P. J., O. L. White and P. M. Schenk (2021), Tectonism and Enhanced Cryovolcanic Potential Around a Loaded Sputnik Planitia Basin, Pluto, J. Geophys. Res., 126, e2021JE006964. https://doi.org/10.1029/2021JE006964

The first group of files (with suffix .mph") contains "cleared" versions of COMSOL Multiphysics (hereinafter "CM") model files. By "cleared", we mean that the "Clear All Meshes" and "Clear All Solutions" tabs in the "Edit" menu of CM have been executed, removing all model results and finite element meshes from the files, which allows compact storage. The results can be recovered by executing the "compute" command within CM. pluto_2Dshell_nominal_cleared.mph produces the model of Figure 5 of the paper (uncompensated basin model). pluto_2Dshell_vt_cleared.mph produces the model of Fig. S9 of the paper (compensated basin model).

Second group of files are matlab scripts (with the suffix .m) to carry out the iteration process.

The third group of files comprise a Generic Mapping Tools script (with suffix .gmt6) for plotting model results and a color palette file (with suffix .cpt) for plotting the A_psi parameter of Simpson.

The last file is a Word document, Guide_to_COMSOL_McGovern_etal_2021_v3.docx, describing how to carry out the iterative load-determining process used to generate the models in the manuscript.
