Exact Critical Coulomb Wedge : tools to compute and display the exact solution of any parameter of Critical Coulomb Wedge
Project description
Exact Critical Coulomb Wedge
ECCW allows to compute the exact solution of any parameter of critical Coulomb wedge (as Dahlen 1984 and Yuan et al. 2015). It allows to draw any of these solutions in the β vs α domain (basal slope against surface slope). Are availables compressive or extensive geological context and fluid pore pressure.
ECCW is under GNU GPL-v3 license.
General informations
ECCW is a python3 library.
A graphical user interface (GUI), written in python3 and using Qt is also available under the name ECCW-GUI.
Installation
Windows
- Install python3 verson of miniconda python environment from https://conda.io/miniconda.html
run downloaded .exe;
at Advanced Options step, tick checkbox named Add Anaconda to my PATH environment variable.
- Launch the windows Command Prompt:
type conda to check that conda is correctly installed;
type pip to check that pip is also correctly installed.
Install ECCW with the following command in the Command Prompt:
$ pip install eccw
ECCW is then available from the Command Prompt by taping eccw or simply from the main Windows menu under the name eccw.
Linux
Installation using pip
Install pip and tk for Python3. On Debian family distributions, you can install these packages using the following command:
$ sudo apt-get install python3-pip python3-tk
Install ECCW with the following command:
$ pip3 install eccw
ECCW is then available from a terminal by taping eccw
Installation from sources
Install the folowing dependancies for python3:
tkpyqt5numpymatplotlibxmltodictOn Debian family distributions, you can install these packages using the following command:
$ sudo apt-get install python3-tk python3-pyqt5 python3-numpy python3-matplotlib python3-xmltodict
Using a terminal with current working directory setted on ECCW sources folder, you can install ECCW with the following command:
$ python3 setup.py install
ECCW is then available from a Terminal by taping eccw
Usage
The following describe usage of ECCW class objects, callable from a python3 shell.
EccwCompute
This the core object that compute the solutions of the CCW problem.
>>> from eccw import EccwCompute >>> foo = EccwCompute(phiB=30, phiD=10, beta=0) >>> foo.show_params() { context : 'Compression' beta : 0.0 alpha : nan phiB : 30.0 phiD : 10.0 rho_f : 0.0 rho_sr : 0.0 delta_lambdaB : 0.0 delta_lambdaD : 0.0 } >>> foo.compute("alpha") ((3.4365319302835018,), (23.946319406533199,))
The result obtained with the compute method is always a tuple of two tuples. The first tuple contains results in inverse fault mechanism, while the second tuple contains results in normal fault mechanism. These tuples can each contain 0, 1 or 2 values, with a total always equal to 0 or 2. Here some more examples with computation of beta parameter::
>>> foo.alpha = 3.436532 >>> foo.compute("beta") ((-1.0516746372768912e-07,), (69.6779628783264,)) >>> foo.alpha = 20 >>> foo.compute("beta") ((), (-3.580929608343892, 43.25889259183777)) >>> foo.alpha = -20 >>> foo.compute("beta") ((36.74110740816224, 83.58092960834391), ()) >>> foo.alpha = -35 >>> foo.compute("beta") ((), ())
Have a look on the plot obtained in next section to understand these results.
EccwPlot
This the core object that plot the solutions of the CCW problem. This object inherits from EccwCompute.
>>> from eccw import EccwPlot >>> foo = EccwPlot(phiB=30, phiD=10) >>> foo.add_curve(inverse={'color':(1,0,0,1), 'label':'inverse'}, normal={'color':(0,0,1,1), 'label':'normal'}) >>> foo.add_point(alpha=3.436532) >>> foo.add_point(alpha=20, style='*', size=10) >>> foo.add_point(alpha=-20, style='s') >>> foo.add_legend() >>> foo.show()
