Possibilities for extensions

+ +The primary objection one may have to this program is that it is still too +slow: 3d computations on reasonably fine meshes are simply too expensive to be +done routinely and with reasonably quick turn-around. This is similar to the +situation we were in when we wrote step-31, from which this program has taken +much inspiration. The solution is similar as it was there as well: We need to +parallelize the program in a way similar to how we derived step-32 out of +step-31. In fact, all of the techniques used in step-32 would be transferable +to this program as well, making the program run on dozens or hundreds of +processors immediately. + +A different direction is to make the program more relevant to many other +porous media applications. Specifically, one avenue is to go to the primary +user of porous media flow simulators, namely the oil industry. There, +applications in this area are dominated by multiphase flow (i.e., more than +the two phases we have here), and the reactions they may have with each other +(or any other way phases may exchange mass, such as through dissolution in and +bubbling out of gas from the oil phase). Furthermore, the presence of gas +often leads to compressibility effects of the fluid. Jointly, these effects +are typically formulated in the widely-used "black oil model". True reactions +between multiple phases also play a role in oil reservoir modeling when +considering controlled burns of oil in the reservoir to raise pressure and +temperature. These are much more complex problems, though, and left for future +projects.
