Trickle-down is the solution (to the planetary core formation problem)</a<>

Scientists have long pondered how rocky bodies in the solar system—including our own Earth—got their metal cores. According to research conducted by The University of Texas at Austin, evidence points to the downwards percolation of molten metal toward the center of the planet through tiny channels between grains

Um, you don’t need a computer model. We already have rocks that illustrate the process of planetary core formation. They’re called stony-iron meteorites, or siderites.

The formation of metallic cores in asteroids is exactly the same as that in planets, except that in asteroids the dominant heating method is radioactive decay of Aluminium-26.
