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:

  1. Run Main_creat_database.py to process and organize model output
  2. Run individual analysis scripts (e.g. 2.plate_dip_gem.py, 8.check_flat_slab.py) for specific analyses
  3. 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)
