This example shows the thermal, magnetic, and orbital evolution of an Earth-like planet using ThermInt, RadHeat, and EqTide. Here we use the "orbit-only" (DB15) tidal model, which is highly idealized. The interior model is 1-D and many free parameters have been tuned to match the modern Earth. This example reproduces the results of Driscoll & Barnes (2015). The generated figures should be compared to their Figures 4 and 5.

Evolution of various properties of a tidally heated Earth-like planet. The initial eccentricity is 0.5, but the semi-major axis varies. The tidal model is very simplified and ignores rotational angular momentum.
