Requirements:

• MATLAB 2020a or later due to the use of tiled layouts.
• Fabio Crameri's scientific colormaps
• Parallel computing toolbox

Description of files:

• The equations solved by the code are derived in the Supplemental Material: 2021GL094421_Supplemental_Material.pdf
• The main driver program that sweeps parameter space is sweep_parameter_space.m. This will produce about 16GB of output as .mat files.
• The file thickening_ice_shell.m solves for the stresses in an initially stress-free thickening ice shell with no heat input.
• Helper subroutines are located in the subdirectory core/
• Files in the benchmarks/ subdirectory can be used to reproduce the results in Nimmo (2004).
