Numerical models
The application to PTA and RTA of specifically designed numerical models is one of the major
technical developments of recent years, especially for KAPPA.
Numerical models address the two major limitations of the modelling methods presented
above: they can model complex geometries, and they can model nonlinear diffusion problems
for which the superposition in time and space of analytical models will not work.
Numerical models are the subject of a dedicated chapter in this book.
