pythonFLAC

Python post-processing and analysis tools for FLAC (Fast Lagrangian Analysis of Continua) geodynamic simulations. Developed for the Master's thesis at National Taiwan University (2022) on flat slab subduction.

flac.py is originally from tan2/geoflac-old. See also the personal FLAC solver fork at chingchenn/geoflac.

DOI: 10.6342/NTU202300033

Usage

Basic workflow:

Run Main_creat_database.py to process and organize model output
Run individual analysis scripts (e.g. 2.plate_dip_gem.py, 8.check_flat_slab.py) for specific analyses
Run Main_snapshot.py for visualization of a specific time frame

Main Scripts

File	Description
`Main_creat_database.py`	Main code for model analysis
`Main_snapshot.py`	Analysis for a specific time frame
`function_for_flac.py`	Core utility functions
`15.slab_analysis.py`	Slab analysis (see requirements below)

Notes

⚠️ 15.slab_analysis.py requires GMT with extra .grd, .cpt, and kkk.csv files, and can only be run on:

140.115.20.181

140.109.81.186

140.110.148.11

⚠️ getDistance in function_for_flac.py is Python 3 only (2021-12-03)
