38 Ionizing Radiation Effects in Electronics
regions that can be simplied or the level of details needed to dene the materials: Is
it needed to include elements that are present in very small proportions in the simu-
lated material? Will they change the result of the simulation?
Similarly, do all interactions processes or all secondary particles need to be
included? Some examples of this issue have been discussed in Section 2.5.3. An
additional method that can be applied is the so-called range-rejection method. It
simply consists of stopping a particle when it cannot leave (or reach) the region of
interest.
To sum up, knowing and understanding the problem at hand before starting to
code can save much development and computation time. One does ...
