AB: We investigate convection in the interior of an extra-solar giant planet using a simple disk-shaped 2D finite volume model with radial gravity. The finite volume method allows us to easily track fluid motion through the center of the disk (the origin point) for a case without a solid inner core. Our anelastic simulations have a cold, impermeable outer boundary and a radial density stratification. A radial heating source simulates heating by gravitational contraction. We compare convection with and without a solid inner core.
