 ## Creating a pipeline network model with the software TESPy
 
-Thermal Engineering Systems in Python (software paper: <https://doi.org/10.21105/joss.02178>, software archive: <https://doi.org/10.5281/zenodo.2555866>) is a software package developed by Francesco Witte. It is capable of simulating coupled thermal-hydraulic status of working fluids in thermal engineering applications. Such system typically involves a circulation network that is composed of pre-defined components including pipes, heat exchangers and different types of turbo machinery. Interested readers may refer to the online documentation (<https://tespy.readthedocs.io/en>) of TESPy for more detailed introduction of the software. The workflow in this part is built based on the benchmark example "A 3-BHE Array Coupled With Pipe Network" from the OpenGeoSys Documentation (<https://www.opengeosys.org/docs/benchmarks/heat-transport-bhe/3d_3bhes_array/>). One can refer to this benchmark and download its latest benchmark files from GitHub (<https://www.opengeosys.org/docs/userguide/basics/introduction/>) for creating the pipeline network TESPy model. The OpenGeoSys and TESPy version used for this tutorial is (OpenGeoSys 6.2.2) and 0.3.3 accordingly.

 The coupled model that is going to be built is demonstrated in Figure 1. It consists of a pipeline network connected with 3 BHEs, a water pump, a virtual heat pump as the consumer, a splitter to split up the feeding fluid flow and a merge to returned flow. These devices are all defined as `components` in TESPy. A full list of available components can be found in the TESPy components module. In the pipeline network, these components are connected with each other through `connections` parts, which are illustrated by the black lines in the figure. With these two main parts, a completely TESPy pipeline network model can be set up.
