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.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|

Michel is the greater expert,
but what happens if the multiple scattering step limitation in water is larger than the sub-block size. In this case, the 'trajectories' - straight lines connecting step-points - would be more zig-zag than in the homogeneous case because the multiple scattering angles and lateral displacements are now calculated based on the geometrical step length.
In any event, the simulation result; i.e. where particles/tracks statistically end up relative to where they started (transverse spread), and their angular deviation from their starting direction, should be independent of whether or not the volume is subdivided into cells. The way these tracks look like in visualization, step points connected by straight lines, might well be very different.
