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)|
Again, sorry nobody addressed your problem until now.
The application manual is wrong in stating that you could use:
G4bool allLocal = true; logicVolumeWithField->SetFieldManager(fEmField->GetLocalFieldManager(),allLocal);
This line is taken from an example code:
Here, fEmField is actually not a field but of class F03FieldSetup and the code in examples/extended/field/field03 is:
logicRadiator->SetFieldManager( fEmFieldSetup->GetLocalFieldManager(), allLocal ) ;
Instead, what you need to do is:
fLocalEquation = new G4EqMagElectricField(fEMfield);
G4int nvar = 8; fLocalStepper = new G4ClassicalRK4( fLocalEquation, nvar );
G4double fMinStep = 0.010*mm; fLocalChordFinder = new G4ChordFinder(fEmField, fMinStep, fLocalStepper);
fLocalFieldManager = new G4FieldManager(); fLocalFieldManager->SetDetectorField(fEmField); fLocalFieldManager->SetChordFinder(fLocalChordFinder);
G4bool allLocal = true ; logicVolumeWithField->SetFieldManager(fLocalFieldManager,allLocal);
