The topic of geological carbon sequestration has provided ample motivation for both experimental and numerical studies of convective flow in porous media, wherein the density contrasts of brine containing dissolved CO2 drive convective dynamics. As part of a PhD project, FEniCSx has been used and extended to study these coupled flow and transport problems computationally. Along the way some more general-purpose tools have also been developed for solving time-dependent and coupled PDEs in FEniCSx, which has enabled novel models to be investigated and prototyped with relative ease, as well as classic models to be benchmarked against well-known results from the literature.
