|
||||
---------------------------------
|
||||
- Added method to PropagatorInField to Get/Set new parameter that
|
||||
controls after how many integration substeps (in one physics step)
|
||||
the Increase of Chord Distance is trigerred.
|
||||
The new method
|
||||
SetIterationsToIncreaseChordDistance()
|
||||
provides control of 'increase' feature introduced in geomnav-V10-05-10.
|
||||
This control is necessary to allow the user to either
|
||||
- disable this change (setting to 0 or large value) or to
|
||||
- change the parameter's value, for earlier/later increase of delta chord.
|
||||
|
||||
This parameter allows the temporary 'relaxation' of the constraint
|
||||
which ensure that each 'chords' is close enough to the section of the
|
||||
curved trajectory that it is approximating.
|
||||
|
||||
( See further explanation of feature & parameter in note for
|
||||
geomnav-V10-05-10. )

|
||||
---------------------------------
|
||||
- G4MultiLevelLocator: Avoid re-estimating endpoint if driver does not
|
||||
ReIntegrate when AccurateAdvance is called.
|
||||
Requires field-V10-05-17
|
||||
|
||||
November 5, 2019 - J.Apostolakis (geomnav-V10-05-15)
|
||||
--------------------------------
|
||||
- G4TransportationManager: Enable worker threads to clone G4Navigator if needed.
|
||||
* Keep first Navigator created for a TM object. By convention that will be
|
||||
the Navigator object of the Master thread (or the only thread).
|
||||
* Other (worker) threads will clone first Navigator, if it has an external
|
||||
sub-navigator registered. This ensures that they clone the ability to
|
||||
navigate in 'external' volume description.
|
||||
- G4VExternalNavigation: added new method for relocation within volume.
|
||||
G4Navigator will call it in LocateGlobalPointWithinVolume().
|
||||
|
||||
November 1, 2019 - P.Arce (geomnav-V10-05-14)
|
||||
--------------------------------
|
||||
- G4PhantomParameterisation: Reverted precision checks to the code in
|
||||
geant4.10.02.p02 to address problem report.
|
||||
Fixes bug #2192
|
||||
|
||||
October 29, 2019 - J.Apostolakis (geomnav-V10-05-13)
|
||||
--------------------------------
|
||||
- Fixed G4Navigator::CharacteriseDaughters:
|
||||
* Use only logical volume's CharacteriseDaughters.
|
||||
Do not check/use whether External Navigator is present.
|
||||
- Added 'direction' back to External Navigation's Inside method.
|
||||
|
||||
October 28, 2019 - G.Cosmo (geomnav-V10-05-12)
|
||||
--------------------------
|
||||
- G4Navigator: define Clone() function to be used instead of copy-constructor
|
||||
(which is kept deleted) for use of explicit cloning.
|
||||
|
||||
October 25, 2019 - J.Apostolakis, G.Cosmo, V.Vlachoudis (geomnav-V10-05-11)
|
||||
-------------------------------------------------------
|
||||
- Added hooks for capability to navigate in 'external' geometry:
|
||||
* base class for external 'sub'-navigator;
|
||||
* new type of 'External' physical volume, to flag volumes for
|
||||
external sub-navigator;
|
||||
* an 'external' sub-navigator can be registered with G4Navigator;
|
||||
* revisions to G4Navigator to dispatch logical volumes with
|
||||
daughters which are of 'external' PV type to that object of
|
||||
type G4VExternalNavigation.
|
||||
Note: 'placement' and 'external' physical volumes cannot be currently mixed
|
||||
inside the same logical volume.
|
||||
- New copy constructor of G4Navigator
|
||||
* needed to 'clone' navigator for G4VIntersectionLocator's 'helper',
|
||||
and potentially for worker threads.

|
||||
---------------------------
|
||||
- Try to relax delta chord condition to solve looping particle issue.
|
||||
|
||||
Introduces temporary 'relaxation' (increase) of the value of delta-chord,
|
||||
to enable larger steps, after a threshold number of iterations (parameter).
|
||||
|
||||
Delta chord ensures that the set of 'chords' approximate the curved trajectory
|
||||
adequately. Each integration step is broken up into segments or substeps
|
||||
for which the sagitta is smaller than 'delta chord.'
|
||||
|
||||
For some tracks this constraint can force a large number of short integration
|
||||
steps, and once the number of steps exceed the 'maximum' they are classed
|
||||
as looping tracks. ( This can occur when the radius of curvature is just
|
||||
larger than delta_chord and a particle is hardly interacting, e.g. if
|
||||
travelling in vacuum or is a muon in a large gas volume. )
|
||||
|
||||
To address this, we increase the value of delta-chord temporarily,
|
||||
after the number of iterations substeps reach a multiple of this threshold.
|
||||
In particular the value of 'delta chord' is doubled when the iterations
|
||||
reach twice this threshold number, and it is doubled again every time the
|
||||
iteration count reaches every other multiple of this value.
|
||||
( Note that delta chord is not changed when the iteration count reaches
|
||||
the threshold number, only its multiples. )
|
||||
|
||||
The initial value of the parameter IterationsChordDistanceThreshold is 100.
|
||||
|
||||
Note: delta-chord is reset to its original value at the end of
|
||||
each call to G4PropagatorInField's ComputeStep method.

|
||||
-------------------------
|
||||
- Use pre-increment wherever possible.
|
||||
|
||||
July 9, 2019 - G.Cosmo (geomnav-V10-05-08)
|
||||
----------------------
|
||||
- Enable UI command "/geometry/navigator/push_notify" which was not
|
||||
setup properly. Addressing problem report #2173.
|
||||
|
||||
July 8, 2019 - G.Cosmo (geomnav-V10-05-07)
|
||||
----------------------
|
||||
- Use constant iterator when possible in G4TransportationManager and
|
||||
G4PartialPhantomParameterisation.
|
||||
|
||||
July 4, 2019 - G.Cosmo (geomnav-V10-05-06)
|
||||
----------------------
|
||||
- Implemented c++11 revision: nullptr, auto, inline data initialisation,
|
||||
alias using statements.
|
||||
- Made G4RegularNavigationHelper a G4ThreadLocalSingleton.
|
||||
- Fixed builds with debug flags.
|
||||
- Code formatting and cleanup.
|
||||
|
||||
July 2, 2019 - J.Apostolakis (geomnav-V10-05-05)
|
||||
----------------------------
|
||||
- G4Navigator: further fix to avoid creating ostringstream object.
|
||||
Now it is created for each step only when the G4DEBUG_NAVIGATION flag
|
||||
is set.
|
||||
( To clarify: the warning was created in ostringstream object if
|
||||
G4VERBOSE was set, but only printed if G4DEBUG_NAVIGATION was set.
|
||||
Now the latter flag is used for both creating and printing. )
|
||||
|
||||
Created to address memory churn reported by memory profiling
|
||||
(Julia/Soon @FNAL).
|
||||
|
||||
June 19, 2019 - G.Cosmo (geomnav-V10-05-04)
|
||||
-----------------------
|
||||
- Fixed compilation warning for unused variable when G4VERBOSE is not set.
