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)|
Have you visualized your geometry (cylinder with spherical end-cap) to confirm it is correctly implemented? (at first glance it looks ok to me).
If you can confirm that the picture is as you'd expect, I suggest you post your problem on the geometry-forum instead.
One other test I can suggest is that you verify that a point is inside your UnionSolid when that points coordinates are either in the cylinder or end-cap. This can be done with code in PrimaryGeneratorAction following logic as at:
e.g. instantiate a new G4Navigator, and use its LocateGlobalPointAndSetup method for the coordinates you want to verify. The G4TouchableHistoryHandle can then be used to obtain the name of the G4LogicalVolume:
It should be your UnionSolid in all cases. If not, this test will help you formulate your posting on the Geometry-Forum (or, in the unlikely event, a G4 bug report).
Hope this helps, Peter
