Nature of problem:
We consider the case of an accidental leakage of high level radioactive waste into the surrounding rock (a porous medium).
We follow the model of Chen and Li to estimate the buildup of radioactivity due to migration from the source. This amounts to the solution of two coupled partial differential equations. The numerical algorithm that we provide solves these equations by a higher order compact finite difference scheme.
The migpor code package needs approximately 50 minutes to run the test inputs. For other cases the run time will depend on the species, the distance and time step.
