2 = "FullInteriorAndExterior" - The simulation will perform the solarcalculation in a manner that models the direct sun (and wheter it is blocked by outdoor context goemetry. It will also ray trace the direct sun on the interior of rooms to distribute it correctly between interior surfaces. Any indirect sun or sun bouncing off of objects will not be modled. Note that, if you use this method without setting the calc_method to PixelCounting, EnergyPlus will give Severe warnings if your rooms have concave geometry (aka. are "L"-shaped). So it is recommended that this solar distribution only be used with the PixelCounting.
