This introduction to geothermal modeling deals with flow and heat transport processes in porous
and fractured media related to geothermal energy applications. Following background coverage of
geothermal resources and utilization in several countries the basics of continuum mechanics
for heat transport processes as well as numerical methods for solving underlying governing
equations are discussed. This examination forms the theoretical basis for five included
step-by-step OpenGeoSys exercises highlighting the most important computational areas within
geothermal resource utilization including heat diffusion heat advection in porous and
fractured media and heat convection. The book concludes with an outlook on practical follow-up
contributions investigating the numerical simulation of shallow and deep geothermal systems.
