This example demonstrates the use of the :doc:`g-function <../modules/gfunction>` module and the :doc:`pipes <../modules/pipes>` module to calculate g-functions using a boundary condition of equal inlet fluid temperature into all boreholes, based on the method of Cimmino [1]. The total rate of heat extraction in the bore field is constant.
The following script generates the g-functions of a rectangular field of 6 x 4 boreholes. The g-function using a boundary condition of equal inlet fluid temperature is compared to the g-functions obtained using boundary conditions of uniform heat extraction rate and of uniform borehole wall temperature.
The script is located in: pygfunction/examples/equal_inlet_temperature.py
