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)|
I may not have the answer to your question, and I actually don't know what the following line does, but in my examples (e.g. field04), I have one more line after PhysicsHasBeenModified:
where physiWorld is the world volume's G4VPhysicalVolume.
Have you actually changed a material in your Construct()? If not, you don't need:
PhysicsHasBeenModified() and the above. That may solve your problem...
I think also - not 100% sure though - when you use the navigator you get with:
you don't have to SetWorldVolume and LocateGlobalPointAndSetup. The kernel should do that for you automatically. This is only required if you have a private Navigator for reasons of returning Touchables from a location outside of the Tracking.
I am not sure I have ever tried to UpdateGeometry when the HP neutron physics list is included in the physics.
