On Enforcing Maximum Principles and Element-Wise Species Balance for Advective-Diffusive-Reactive Systems
… and the absolute temperature naturally attain non-negative values. Moreover, the governing equations of an advective-diffusive-reactive system are either elliptic (in the case of steady-state response) or parabolic (in the case of transient response) partial differential equations, which …

Structure-Preserving High Performance Computational Methods for Transport in Porous Media
… suffer from are the inability to meet the non-negative constraint under anisotropic diffusion (i.e., they violate dis- crete maximum principles) and the inability of the standard finite element formulation to ensure local mass balance. Moreover, there is no platform-agnostic performance …
