Calculation of g-functions with uniform borehole heat extraction rates
**********************************************************************

This example demonstrates the use of the :doc:`g-function <../modules/gfunction>` module
to calculate *g*-functions using a boundary condition of uniform and equal
heat extraction rate for all boreholes, constant in time.

The following script generates the *g*-functions of rectangular fields of
3 x 2, 6 x 4 and 10 x 10 boreholes. *g*-Functions are verified against the
*g*-functions presented by Cimmino and Bernier [1]_.

The script is located in:
`pygfunction/examples/uniform_heat_extraction_rate.py`
