Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

examples/extended/electromagnetic/TestEm3 is similar to N03 (only a little more general). It containts its own StepMax 'process' class (and its messenger) registered in PhysicsList. In macro lockwood.mac, the step size is limited in absorber 2.
