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 suggest using the following methods of PropagatorInField to
void SetMaxLoopCount( G4int new_max );
to enable it to go further in case it is simply taking too many substeps in order to integrate in the much-varying field. The current default is 1000.
G4int SetVerboseLevel( G4int verbose );
if you give it a value of 2 or 3 it print some more information which could be useful in identifying the problem.
To find the G4PropagatorInField, please use the G4TransportationManager. Its method static G4TransportationManager* GetTransportationManager() gives the singleton's pointer and the method G4PropagatorInField* GetPropagatorInField() provides that.
If you can provide more information from these I will be glad to try to assist.
Best regards, John Apostolakis
