GeoNDT: a fast general-purpose computational tool for geotechnical non-destructive testing applications

Project description

GeoNDT is a fast general-purpose computational tool for geotechnical non-destructive testing applications. GeoNDT is flexible, general-purpose, and can be used seamlessly for advanced signal interpretation in geophysical laboratory testing including the bender element (BE) and ultrasonic pulse velocity (UPV) tests, characterization of complex multiphase geomaterials, in-situ shallow seismic geophysics including the falling weight deflectometer (FWD) and multichannel analysis of surface waves (MASW) tests. The advanced physics-based signal interpretation feature of GeoNDT allows the quantitative characterization of geophysical and geomechanical properties of geomaterials and multilayered geosystems independently without making any simplified assumptions as common in the current practice.

Quick start

Install (only for Linux):

pip install geondt

To install development version, clone this repo and install in Linux:

git clone https://github.com/siglab/geondt

cd geondt

pip install -e .

To install development version, clone this repo and install in Windows:

git clone https://github.com/siglab/geondt

cd geondt

python setup.py build --compiler=mingw32

python setup.py install

Usage

The GeoNDT can efficiently study the three-dimensional wave propagation within soil specimens in the BE test. Sample code is given as follows:

>>> import numpy as np
>>> from geondt import one_phase_dynamic
>>> import  json
>>> with open('BE_dry.json', "r") as f:
        data = json.load(f)
>>> BE = one_phase_dynamic(**data["input"])
>>> signal = BE.run_f()

Troubleshooting

The installation procedure assumes that the Fortran compiler such as Gfortran and Lapack library are installed on your system. To install Gfortran and Lapack in Linux:

sudo apt install gfortran
sudo apt-get install liblapacke-dev checkinstall
export gfortran="/home/kay/gcc-4.8.5/bin/gfortran"

To install Gfortran and Lapack in Windows:

* Use MinGW <https://sourceforge.net/projects/mingw-w64/> to get Gfortran. Make sure the Mingw is added to the system path.
* Then add the liblapack.a file (can be found under lib folder in this respiratory ) in the MinGW folder (C:\mingw64\x86_64-w64-mingw32\lib).
