Hello, we are running a G4 (Geant4/10.02.p03) on a computing cluster. And our code, that normally works is experiencing an error (see the output below). Most of the jobs fail with something like this after a few thousand events. The gamma energy is always some small fraction of an MeV. If someone can give a hint, that would be helpful. Output of the crash is below (gamma enters a NaI (Z=53)): =============================================================================== G4VCrossSectionDataSet::GetCrossSection per element ERROR: there is no cross section for gamma E(MeV)= 0.0375935 for Z= 53 In /dev/shm/ebuser/Geant4/10.02.p03/iccifort-2016.4/geant4.10.02.p03/source/processes/hadronic/cross_sections/src/G4VCrossSectionDataSet.cc, line 146: ===> G4VCrossSectionDataSet::GetElementCrossSection is absent -------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : had006 issued by : G4HadronicProcess::PostStepDoIt In /dev/shm/ebuser/Geant4/10.02.p03/iccifort-2016.4/geant4.10.02.p03/source/processes/hadronic/cross_sections/src/G4VCrossSectionDataSet.cc, line 146: ===> G4VCrossSectionDataSet::GetElementCrossSection is absent Call for G4ElectroVDNuclearModel Target element I Z= 53 A= 127 Unrecoverable error in the method ApplyYourself of positronNuclear TrackID= 1 ParentID= 0 e+ Ekin(GeV)= 0.0404746; direction= (0.0796135,-0.00414759,0.996817) Position(mm)= (-30.4713,-5.4322,688.119); material G4_SODIUM_IODIDE PhysicalVolume <NaI> ApplyYourself failed *** Fatal Exception *** core dump ***
