Brief description

Rift processes in continental and oceanic settings have been thoroughly studied through observational analysis and numerical models. However, limited observations and lack of numerical modelling showing rift evolution in Large Igneous Province settings leave a comprehensive understanding of rift mechanics unresolved. This dataset consists of input files for the creation of numerical models showing the thermo-mechanical evolution of rifting in Large Igneous Province settings, focusing on the William's Ridge-Broken Ridge study case."

Model runs in the study used dealii 9.3.0.

The ASPECT version can be found at: https://github.com/EstherHeck/aspect/tree/fastscape_update_again_erosional_base_level-undo2780-before-rebase-on13mai22-Kais-and-ZhiChens-Version

The FastScape version can be found at:
https://github.com/Djneu/fastscapelib-fortran

To install this version of ASPECT with FastScape:

1. Create a build directory for fastscape and compile it with an added flag for creating a shared library.
cmake -DBUILD_FASTSCAPELIB_SHARED=ON /path/to/fastscapemake
make

2. Compile ASPECT with a flag FASTSCAPE_DIR pointing to the fastscape build folder with the shared library
cmake -DFASTSCAPE_DIR=/path/to/fastscape/build -DDEAL_II_DIR=/path/to/dealii -DCMAKE_BUILD_TYPE=Release /path/to/aspect
make

*Note: ASPECT will still compile and install even if a FastScape version is not found. During cmake, it should state whether or not FastScape was found, if it was not you'll need to rerun cmake.
*Note: For FastScape visualization add the following line to your .bashrc: export GFORTRAN_CONVERT_UNIT=‘big_endian’
