We present Galerkin finite element computations of heat transfer and fluid dynamics in high-temperature materials processing systems. Examples are presented of how large-scale numerical simulations have been used to gain insight into the workings of several processes, specifically the growth of large, single crystals and the flow characteristics of molten glass. These systems are characterized by nonlinear interactions between field and interfacial phenomena - the transport of momentum, heat and mass and effects of solidification and capillarity. Additional complications are caused by the effects of internal radiative energy transport within participating media (internal radiation).
