timflow#
timflow is a Python package for the modeling of multi-layer flow with analytic elements. Is is split into two main submodules timflow.steady for steady-state flow and timflow.transient for modeling transient flow. Both modules may be applied to an arbitrary number of aquifers and leaky layers. The head, flow, and leakage between aquifers may be computed semi-analytically at any point in space and time. The design of timflow 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. timflow is coded in Python and uses numba to speed up evaluation of the line elements and inverse laplace transforms.
The transient modeling submodule is based on the Laplace-transform analytic element method. The solution is computed analytically in the Laplace domain and converted back to the time domain numerically usig the algorithm of De Hoog, Stokes, and Knight.
