dispersion equation with an anisotropic dispersion tensor is solved using COMSOL
Multiphysics

. The reaction term (
8.41
) is computed at each node and each time
level. In order to evaluate formula (
8.41
), the concentrations of the species need to
be known. They are obtained within a MATLAB
speciation M-file, which is
called by COMSOL Multiphysics. The M-file looks as follows:
®
Using the software combination of this topic, it is thus possible to treat reactive
transport in several space dimensions.
