KW - Closed-loop geothermal model, penalty finite element method, error estimate, numerical test.
AB - <p style="text-align: justify;">In this article, we give a penalty finite element method for the steady-state closed-loop
geothermal model. Firstly, we construct the stationary penalty closed-loop geothermal equations.
Secondly, we propose a finite element method for the penalty system and deduce error estimates.
Finally, some numerical experiments are used to illustrate the theoretical results of the presented
method.</p>
