timml 4.0.4

Steady multi-layer AEM model


TimML is a computer program for the modeling of steady-state multi-layer flow with analytic elements and consists of a library of Python scripts and FORTRAN extensions. TimML may be applied to an arbitrary number of aquifers and leaky layers. The head, flow, and leakage between aquifers may be computed analytically at any point in the aquifer system. The design of TimML is object-oriented and has been kept simple and flexible. New analytic elements may be added to the code without making any changes in the existing part of the code. TimML is coded in Python; use is made of FORTRAN extensions to improve performance.

TimML Changes

Version 4.0

In version 4.0, the numbering of the layers in TimML has changed. Layers are numbered from the top down starting at number 0. (in TimML versions prior to 4.0, layer numbers started at 1).


Python versions:

TimML requires Python 2.7 and can be installed from PyPI. The PyPI installation includes compiled versions of the FORTRAN extension for both Windows and MaxOS.


TimML requires NumPy 1.9 (or higher) and matplotlib 1.4 (or higher). T

For base Python distributions:

To install TimML, open a command prompt and type:

pip install timml

To update TimML type:

pip install timml --upgrade

To uninstall TimML type:

pip uninstall timml
