Deterministic mathematical models of the Maddock melting mechanism based on analytical and finite‐difference solution methods are surveyed and classified according to the key assumptions involved. It has been concluded that the rigid solid bed concept coupled with a consistent non‐Newtonian analysis of the melt flow pattern, including cross‐channel circulation, leads to superior results. It is suggested that the development of the melting theory for the Maddock mechanism as an engineering analytical tool is virtually complete.
