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)|
The user is required in Geant4 to supply the method (see G4Field)
virtual void GetFieldValue( const double Point, double *fieldArr ) const = 0;
// Given the position time vector 'Point',
// return the value of the field in the array fieldArr.
// 1) The 'Point' vector has the following structure:
// Point is x ( position, in Geant4 units )
// Point is y
// Point is z
// Point is t ( time, in Geant4 units )
See, for example:
on how the arguments of this method are filled from G4Step and G4Track information.
I am not aware of a G4 example which would exhibit a time varying field.
