What's new in Geant4 11.2.1

Mar 2, 2024
  • ist f fixes included in this public patch since the public release 11.2.0:
  • Cnfiguratin
  • CMake:
  • Added -F flag n macS with a framewrk build f Qt.
  • Addressing prblem reprt #2589.
  • Fixed detectin f SQt/Xt packages, by manually checking versins f
  • fund packages. Geant4 nly requires a minimum versin.
  • Gemetry:
  • slids/CSG:
  • In wrapper G4UTrap, use GetThetaCsPhi() and GetThetaSinPhi() in
  • methd GetVertices(); this vercmes a prblem with trapezid reprted
  • in CMSSW after migratin t VecGem 1.2.6.
  • Als fixed typ in methd SetAllParameters(), setter used in
  • parameterisatin f shape dimensins.
  • Glbal:
  • G4PhysicsMdelCatalg: added ID fr the Light-In QMD mdel.
  • Updated date and versin fr 11.2.1.
  • Physics Lists:
  • cnstructrs/electrmagnetic
  • G4GammaGeneralPrcess: fixed sampling f mun pair prductin.
  • Addressing prblem reprt #2543.
  • G4EmStandardPhysics_ptin3: restre step limit type t use
  • 'fUseDistanceTBundary' and set default RangeFactr frm 0.03 t 0.04,
  • fixing inaccuracy in medical benchmarks.
  • cnstructrs/gamma_lept_nuclear
  • G4NeutrinPhysics: fixed neutrin physics instantiatin.
  • Addressing prblem reprt #2594.
  • Prcesses - Electrmagnetic:
  • dna
  • G4DNABrnAngle: fixed numerical prblem; added prtectin fr csTheta;
  • use relativistic frmula fr maximum energy transfer t delta-electrns.
  • lweneegy
  • G4MicrElecInelasticMdel_new: fixed Cverity reprt fr memry leak at
  • exit. Minr cde cleanup.
  • G4MicrElecLPhnnMdel: minr cde cleanup.
  • standard
  • G4InICRU73Data: fix fr the case when target material has an element
  • with Z>92; imprved debug printuts. In the Lindhard-Srensen mdel t
  • cmpute dEdx the first try is t take it frm ICRU73 r ICRU90 data,
  • if this class returns zer, then dEdx is cmputed frm G4GenericIn
  • and effective charge. Addressing prblem reprt #2586.
  • utils
  • G4VEmPrcess, G4VEnergyLssPrcess: minr CPU ptimisatin with
  • reductin f number f calls fr lg() f kinetic energy.
  • xrays
  • G4GaussXTRadiatr, G4VXTRenergyLss: flexible summatin in SpectralXTRdEdx;
  • clean-up in GetStackFactr() based n std::cmplex methds.
  • In G4Scintillatin::sample_time(), refactred the scintillatin time
  • sampling.
  • Prcesses - Hadrnic:
  • crss_sectins
  • G4KkulinMunNuclearXS: use faster interface t G4PhysicsVectr.
  • G4ElectrNuclearCrssSectin: added lw-energy limit f 100 MeV fr
  • crss-sectin.
  • management
  • G4HadrnicPrcess: explicitly define crss-sectin type per particle
  • type, this might prvide sme CPU speedup.
  • mdels/de_excitatin
  • G4FermiBreakUpVI, G4FermiFragmentsPlVI: fix in prductin f fake
  • excited ismeres, by mving the check n lifetime limit t the Initialise()
  • methd f the mdel, allwing t change this limit in an applicatin;
  • d nt cnsider decay chains with n final state.
  • Addressing prblem reprt #2584.
  • G4StatMFChannel: replaced use f C-arrays with std::vectr, clearing
  • cmpilatin warnings n gcc cmpiler when LT settings are enabled.
  • mdels/lend
  • Fixed cmpilatin errr n recent Windws VC++ cmpiler 17.8.3 fr use
  • f std::isfinite(). Addressing prblem reprt #2582.
  • Fixed cmpilatin warnings n gcc cmpiler when LT settings are
  • enabled.
  • mdels/particle_hp
  • G4ParticleHPFissinFS, G4ParticleHPFFFissinFS: added extra prtectins
  • against cases when fissin data are nt available fr sme istpes.
  • Addressing prblem #2590.
  • G4ParticleHPFSFissinFS, G4ParticleHPFissinBaseFS: replaced use f
  • C-arrays with std::vectr, clearing cmpilatin warnings n gcc
  • cmpiler when LT settings are enabled.
  • qmd
  • Fixed mdel ID (mdel_LightInQMDMdel) in G4LightInQMDReactin.
  • radiactive_decay
  • G4Radiactivatin: added DBL_EPSILN check n transitin energy fr
  • metastables t prevent creatin f zer energy levels which have n
  • decay prducts.
  • G4BetaPlusDecay, G4BetaMinusDecay: fixed sampling algrithm.
  • Addressing prblem reprt #2588.
  • Run:
  • Crrectly reprt number f threads frm G4TaskRunManager.
  • Tracking:
  • G4TrackingMessenger: fixed Cverity reprt fr memry leak at exit,
  • by mving static thread-lcal variable t becme class member, as
  • G4TrackingManager and its messenger are thread-lcal by nature.
  • Examples:
  • basic/B2
  • Updated PrimaryGeneratrActin::GeneratePrimaries() in B2a and B2b
  • examples t avid placing f the initial psitin n the wrld
  • bundary. Updated READMEs.
  • extended/electrmagnetic/TestEm1
  • Updated initial gun psitin in PrimaryGeneratrActin t nt lay n
  • the wrld vlume surface.
  • extended/electrmagnetic/TestEm5
  • Updated initial gun psitin in PrimaryGeneratrActin t nt lay n
  • the wrld vlume surface.
  • In TrackingActin, added a prtectin against ptential wrng argument
  • t std::acs(), rarely happening fr very high energy prjectile
  • particles.
  • extended/electrmagnetic/TestEm11
  • Updated initial gun psitin in PrimaryGeneratrActin t nt lay n
  • the wrld vlume surface.
  • extended/electrmagnetic/TestEm16
  • Updated READMEs t dcument all macrs.
  • extended/medical/dna/neurn
  • Cleanup t reduce number f Valgrind warnings; applied cding style
  • recmmendatins; remved cmmented lines, remved unused methds;
  • substituted C-arrays with vectrs; imprved algrithm f reading f
  • data file.
