|
|
|
|
13 March 2026
|
|
|
|
List of fixes included in this public patch since release 11.4.0:
|
|
|
|
o CMake
|
|
-----
|
|
+ Use CMake 3.16-3.19 compatible construction of interface libraries.
|
|
Addresses problem report #2700.
|
|
Fixed logic error in construction of link interface to such interface
|
|

|
o Geometry
|
|
--------
|
|
+ magneticfield:

|
|
|
|
o Global
|
|
------

|
|
of latter; prevents fatal G4Exception when only low ID G4Cache elements
|
|
are accessed.
|
|
Protect debug warning printout from G4Cache destructor within 'g4cdebug'
|
|
flag as it was originally intended. Addressing long-standing false-positive

|
|
addressing problem report #2683.
|
|
Fix in ComputeStringMatchScore(..) in setting number of elements for a
|
|
QVector; use G4 types where appropriate. Fixed compilation warning for
|
|
implicit type conversion on macOS/XCode.
|
|
|
|

o Physics Lists
|
|
-------------
|
|
+ constructors/electromagnetic:
|
|
o G4EmStandardPhysics_option4: added possibility to use external dEdx
|
|
tables for ions, through substitution of the G4LindhardSorencenIonModel
|
|
model class by G4IonParameterisedModel. Addressing problem report #2703.
|
|
+ constructors/hadron_elastic:
|
|
o G4ChargeExchangePhysics, G4ChargeExchangemessenger: added two different
|
|
biasing factors for pions and kaons (request by NA64).
|
|
+ constructors/hadron_inelastic:
|
|
o In G4HadronInelasticQBBC, return back cross-section
|
|
G4ParticleInelasticXS for protons as it was in release 11.3.
|
|
o Fixed segmentation fault occurring on Linux/gcc15/Debug/CXX23, caused
|
|
by in-scope destruction of G4NeutronPHPBuilder instance used by
|
|
G4NeutronBuilder in G4HadronPhysicsShielding.
|
|
+ lists:
|
|
o G4PhysListFactory: trivial fix for reported Coverity defect.
|

|
|
---------------------------

|
quantum entanglement papers.
|
|
|
|
o Processes - Hadronic
|
|
--------------------
|
|
+ cross_sections:
|
|
o G4ChargeExchangeXS: added two different biasing factors for pions and
|
|
kaons (requested by NA64). Removed debug printout and fixed reported
|
|
Coverity defect.
|
|
+ models/binary_cascade:
|
|
o Fixed reported Coverity defects to avoid parameter string copy in
|
|
G4BinaryCascade.
|
|
o G4GeneratorPrecompoundInterface: added G4HadronicException header.
|
|
+ models/cascade:
|
|
o Directly use std::cbrt(double) in G4InuclSpecialFunctions, as now
|
|
standard and available in <cmath>, replacing old ad-hoc implementation.
|
|
Minor code formatting.
|
|
+ models/coherent_elastic:
|
|
o G4ChargeExchange: fixed bug in sampling of scattering angle for kaons.
|
|
o G4ChargeExchange, G4HadronElastic, G4LMsdGenerator: minor optimisation.
|
|
+ models/fission:
|
|
o Fixed reported Coverity defects in G4fissioner for avoiding unnecessary
|
|
copy of strings.
|
|
o Fixed layout of G4fissionEvent class.
|
|
+ models/inclxx:
|
|
o In G4INCLCrossSectionsAntiparticles, corrected wrong formulae with
|
|
isospins concerning the cross-sections N Nbar -> N Nbar + 2 pions.
|
|
o In G4INCLNNToNSK2piChannel, fixed 'iso' condition.
|
|
o Fixed reported Coverity defects for use of std::move() in G4INCLCascade
|
|
and G4INCLNbarAtrestEntryChannel. Use G4 types consistently.
|
|
+ models/nudex:
|
|
o Fixed reported Coverity defects in G4NuDEXPSF for avoiding unnecessary
|
|
copy of strings.
|
|
+ models/particle_hp:
|
|
o G4ParticleHPContAngularPar: reduced allocator fragmentation and memory
|
|
churn in BuildByInterpolation() by removing unconditional deep copies
|
|
of input angular distributions. Copies are now created only in case of
|
|
self-aliasing, preserving correctness while avoiding excessive per-call
|
|
heap allocations. Addressing problem report #2630.
|
|
o G4ParticleHPNBodyPhaseSpace, G4ParticleHPInelasticCompFS: added
|
|
G4HadronicException header.
|
|
+ models/parton_string:
|
|
o Added G4HadronicException header where missing for self-consistency.

|
+ models/theo_high_energy:
|
|
o G4TheoFSGenerator: added G4HadronicException header.
|
|
+ stopping:
|
|
o G4HadronStoppingProcess, G4MuonicAtomDecay: added G4HadronicException
|
|
header.

|
|
|
o Processes - Solid state
|
|
-----------------------
|
|
+ channeling:
|
|
o In G4ChannelingMaterialData, fixed reported Coverity defects for string
|
|
parameters copying. Use consistently G4 types and minor code formatting.
|
|
|
|
o Run
|
|
---
|
|
+ Introduced UI command "/run/undertakeOptimisation" to force geometry
|
|
optimisation and added to G4RunMessenger.
|
|
+ Re-enabled automatic instantiation of G4MaterialScanner in G4RunManager;
|
|
material scanner is instantiated only for the master thread.
|
|
Fix in G4MaterialScanner to delete G4Event object at the end of each
|
|
event and make sure geometry is optimized before starting the scan.
|
|
In G4MSSteppingAction, fixed average A and average Z taking number of
|
|
atoms into account. In G4MatScanMessenger, prevent material scanner
|
|
UI commands from broadcasting to worker threads; material scanner is
|
|
centrally managed by the master thread.
|
|
|
|
o Visualization
|
|
-------------
|
|
+ modeling:
|
|
o In G4PhysicalVolumeModel, fix to replace the helper class
|
|
G4PhysicalVolumeModelTouchable with a temporary G4TouchableHistory
|
|
object when calling a nested parameterisation, building and maintaining
|
|
a private G4NavigationHistory.
|
|
+ gMocren:
|
|
o Fixed reported Coverity defect for unnecessary string copy in G4GMocrenIO.
|
|
+ OpenGL:
|
|
o In G4OpenGLQtViewer, fix in G4wheelEvent() for Qt version < 5.14.
|
|
Addressing problem report #2688.
|
|
o G4OpenGLViewer: removed unnecessary #include statements.
|
|
+ ToolsSG:
|
|
o G4ToolsSGSceneHandler: obtain applicable auxiliary edge flag.
|
|
In AddPrimitive(..), fixed position of daughter of cloud-represented
|
|
volumes. Addressing problem report #2691.
|
|
+ Tree:
|
|
o Moved 'fVerbosityGuidance' to G4ASCIITree factory to fix sanitizer
|
|
warnings. Addressing problem report #2699.
|
|
|
|
o Examples
|
|
--------
|
|
+ advanced/dna/moleculardna:
|
|
o Fixed display of error for 'SSBm_yield' in analysis macros.
|
|
+ extended/exoticphysics/channeling/ch2:
|
|
o Correction in main() for fixing error at the end of execution when
|
|
G4ChannelingFastSimModel is switched off.
|
|
o Corrections in plot labels and some comments in the python scripts.
|
|
o Fixed CMake script to copy also Jupyter notebook in the build folder.
|
|
o Small corrections in comments in macro.
|
|
+ extended/medical/dna/chem6:
|
|
o Fixed energy unit for LET(100).
|
|
o Cleanup implementation in main(): use default random engine MixMax and
|
|
use auto whenever appropriate.
|
|
o Set 1 as number of threads in beam.in to clear run-time warnings and
|
|
fix Windows crash on exit.
|
|
+ extended/medical/dna/dnadamage2:
|
|
o Cleanup implementation in main(): use default random engine MixMax and
|
|
use auto whenever appropriate.
