FastIsostasy.jl

❄ Fast and flexible glacial isostatic adjustment on CPU and GPU.

Upgrade to v2.0!

FastIsostasy.jl has been refactored to fix some performance issues, offer a more versatile API and propose new features. FastIsostasy v2.0 is currently being tested and will be out soon. If you are using v1.0, we strongly encourage you to uprade to v2.0 when it comes out!

GlacialCycle

FastIsostasy is a collection of models to compute the regional glacial isostatic adjustment (GIA) resulting from changes in the surface load (ice, liquid water and sediments). It is:

  • Accessible: you can set up complex simulations with only a few lines of code, as demonstrated for the case of the last glacial cycle.
  • Flexible: you can easily permute parameters and modelling choices to play Earth System Modelling like it's lego.
  • Performant: the results obtained only marginally differ from those obtained by 1D and 3D GIA models, while displaying a speed-up of 2 to 6 orders of magnitude.

Getting started

FastIsostasy.jl is a registered julia package. To install it, simply run:

using Pkg
Pkg.add("FastIsostasy")

How to read the docs?

If you want a quick introduction to GIA, please go to Quick intro to GIA. If you want to have a thorough but still accessbile introduction to GIA, we highly recommend reading Whitehouse et al. (2019). If you want to get started right away, feel free to directly go to the Tutorial. If you face any problem using the code or want to know more about the functionalities of the package, visit the API reference. If you face a problem you cannot solve, please open a GitHub issue with a minimal and reproduceable example. We also welcome feature requests!
