As the hot and dense matter created in relativistic heavy-ion collisions expands and cools, theory must accurately treat its thermodynamic properties as well as its transport behavior. Because gradient terms probe the local environment within the evolving system, they are important in modeling the growth of thermal fluctuations, especially near a critical point, where knowledge of the size and spread of correlations is crucial. This paper demonstrates how gradient terms can be incorporated into the hydrodynamic equations of motion and how those modifications can be consistently applied to all thermodynamic quantities.
