Lets look at the geometry first. We want to define a rectangular domain of width $5 km$ and depth $6 km$ below the surface of the Earth. The domain is subject to a few conditions. The temperature is known at the surface and the basement has a known heat flux. Each side of the domain is insulated and the aim is to calculate the final temperature distribution. @@ -238,7 +238,7 @@ It is now possible to start defining our domain and boundaries. -The curve defining our clinal structure is approximately located in the middle of the domain and has a sinusoidal shape.
