empymod 1.2.0

ElectroMagnetic Python forward MODeller (1D)

Electromagnetic modeller in Python

The electromagnetic modeller empymod can model electric or magnetic responses due to a three-dimensional electric or magnetic source in a layered-earth model with vertical transverse isotropy, electric permittivity, and magnetic permeability, from very low frequencies to very high frequencies.

Installation & requirements

Just add the path to empymod to your python-path variable.

Alternatively, to install it in your python distribution (linux), run:

python setup.py install

Required are python version 3.4 or higher and the modules NumPy and SciPy. If you want to run parts of the kernel in parallel, the module numexpr is required additionally.

Documentation

The manual for empymod can be found at http://empymod.readthedocs.io. Consult the manual for further information and a list of TODOs.

Notice

This product includes software that was initially (till 01/2017) developed at The Mexican Institute of Petroleum IMP (Instituto Mexicano del Petróleo, http://www.imp.mx). The project was funded through The Mexican National Council of Science and Technology (Consejo Nacional de Ciencia y Tecnología, http://www.conacyt.mx).

This product is a derivative work of the following two publications and their publicly available software:

Both pieces of software are published under the SEG disclaimer. Parts of the modeller emmod from Hunziker et al, 2015, is furthermore released under the Common Public License Version 1.0 (CPL).

Citation

I am in the process of publishing an article regarding empymod, and I will put the info here once it is a reality. If you publish results for which you used empymod, please consider citing this article. Also consider citing the two articles given above, Hunziker et al, 2015, and Key, 2012, without which empymod would not exist.
