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.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Hi, For the first question, the step is always limited by geometry boundary. It means PostStep should be on the "GeomBoundary" if the track goes on the interface of different geometry. Therefore, the deposited energy only belongs to one geometry and not shared by two geometry. This is basic criteria. If you are using ROGeometry or RegularNavigation, then you have to care about it by yourself. For the second question, I recommend to post it to physics related category. Best regards, Tsukasa Aso
