Using COMSOL Multiphysics to Model Ground Heat Exchange

In building physics it is a fact that a large part of the knowledge available from research is not applied in construction and design. The main reason for this is that the physics often include nonlinear field problems that are difficult to solve for the ordinary engineer.

With a software that allows the combination of many different physics, the solvability of such problems increases.

The examples here are intended to show the possibilities and results that can be reached with COMSOL Multiphysics, but there are of course many more applications that could be treated in this way.
