1) Pending problems
1.1) Pending problems reported by Sang Hyun Ko:
- Cannot setup Birk's constant as material property.
- No analogy to G4PVParametrized. Unclear if a solution is possible.
1.2) Add GFlash parameterisation to DDG4 (issue #802)
1.3) Problems with ROOT-python compatibilities (issue 842)
==> Waiting for Paul to provide a PR
1.4) DDG4: isotropic gun distribution also forces uniform momentum distribution #862
==> Waiting for Wouter to provide PR
1.5) std::terminate handling and Geant4 (CMS request)
==> Assigned to Markus
1.6) DD4POD: Waiting for PR from Whitney
1.7) Geant4 11.0 beta open issues between snapshot compilation
1.8 PluginFactoryBase::make_return problem with longs (Issue 875)
2) Closed issues and fixed problems
3) Round table
3.1 Wouter: DDG4 particle handler has SEGV. Problematic are "stable" particles which decay
and are given to Geant4. These are double-deleted and cause problems. The solution is to add
these to the rejection list so that they are excluded from Geant4 processing.
3.2 Carl: NTR
3.2 Andre: some plugin problems still to be understood.
3.3 Sylvester: NTR
3.4 Frank: Interest in GFlash
Next meeting in 2 weeks 16.December 2021
