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|
|3||3||All||3 levels / all levels (all postings)|
Hi Dan, > I have a strange bug in my simulation where I can run say 5 protons > through a magnetic field and through some simple box shaped materials > quickly and apparently correctly, but when I move a box a small amount > and rerun the simulation runs forever and the memory usage blows up > from ~9Mb to 200+ Mb. you should first verify that you are NOT introducing overlaps; if so, verify if the memory growth is happening at initialisation time; try to run your application with: /run/verbose 2 This should print out a statistics (memory, time) of the voxels created for optimise the geometry. If you indentify a particular volume for which the optimisation is much consuming, you can try to manually tune the optimisation for the volume concerned (say, 'yourLogicalVolume') in your code; try with: yourLogicalVolume->SetSmartless(1.0); // ... or 0.5 In some rare cases (depending on the geometry setup) it may be necessary to manually tune the geometry optimisation...
