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.
Python versions:
TimML requires Python >= 3.5 and can be installed from PyPI, or conda-forge. The PyPI installation includes compiled versions of the FORTRAN extension for both Windows and MacOS.
Dependencies:
TimML requires NumPy >=1.12, Scipy >=0.19 and matplotlib >=2.0.
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
For Anaconda Python distributions:
To install
conda install -c conda-forge timml
To update

TimML version 5 is a total rewrite and is not backwards compatible with previous TimML versions. TimML version 5 is intended to be compatible with TTim. TimML version 5 has many new features and elements, the code base is Python 3, and the object oriented design is much simpler. TimML version 4 remains available through the timml4 branch.
