While 1-D studies have proven the effectiveness of stellar fluxes at altering the atmospheric mass and composition for sub-Jupiter mass planets, there remains much that is uncertain with regard to the larger-scale, multidimensional nature of such \"planetary wind\" flows. In this paper we use a new radiation-hydrodynamic platform to simulate atmospheric evaporative flows.
