Data supporting "Transition between mechanical and geometric controls in glacier crevassing processes".

The folders:

• results_Geometrical_Regime
• results_Mechanical_Regime
• results_3D
• results_varyingLengthSlope
• results_varyingVelocity

contain the data for spacing and depth of the crevasses in the different simulations. Each simulation folder is named after the ice thickness H and cohesion c. For example, H300c2 means an ice thickness of 300m and a cohesion of 2MPa.

The simulation files contain data measured every 10 frames. Empty files imply two possibilities:
-the crevasse(s) are away from the window measurement (the window is approximately 1500m wide around the obstacle).
-No crevasses are observed or at least no distinguishable enough.

The python code readDataMeasuredInSimulations.py use the readDataPP class to plot the measures from the previous folders.
All the figures from the paper can be reproduced using this code.

The full simulation results cannot be transfered as a supplementary material as it is too large (20Go for each simulation). However we provide two full result files: H300_c0_4.abc and  H100_c2.abc. We provide an example of the init.lua file used to launch a simulation with given parameters and configurations. The configurations used in the simulations are all provided in the geometry.zip file.

A version of the MPM numerical model can be found in a previous publication at https://www.nature.com/articles/s43247-021-00179-7.
