The figure below shows the normalized density of flow from the formation into the fracture.
The red curve corresponds to the Uniform Flux fracture. At very early time the infinite
conductivity solution will follow this profile. However this changes rapidly until it stabilizes at
late time to the blue curve, showing that most of the flow at late time comes from the tips of
the fracture, which are more exposed to the rest of the formation than the center part.
