Present: A. Tolosa, A. Sailer, F.Gaede, J.Smiesko, M.Frank, S. Banerjee, T.Madlener

1) Pending problems

----

1) DDDigi TBB code needs migration to new oneAPI TBB interfaces (Issue 901):
      Clash between Intel oneapi TBB and classic TBB.
      -- Wouter promised to look into.
2) Issue 918: Should be addressed by PR920. Waiting for feedback.
                        HepMC3 reader with Pythia8 Argantyr generator: status checker not implemented
                       ==> addressed by PR 935 ?
3) Issue 921: EDM4hep output MCParticleCollection should be named MCParticle
                       ==> Thomas promised to investigate a solution.
4) Issue 940: Integration of external library (CRY) for cosmic ray generation in DDG4 simulation: on hold
5) Issue 970: Support for digitization in ddsim: on hold
6) Issue 984: DD4hep output with MarlinDD4hep
7) Issue 988: Propagate cross section to the simulation (on hold)
                        ===> likely a EDM4hep problem
8) Issue 994: Geometry checksum/hash for consistency checks between simulation and reconstruction steps (on hold)
9) Issue 985: dummy material exported into gdml is not recognized by Geant4 (waiting for Markus)
10) Issue 1004: DDG4: Particle charge is not properly propagated from the input stage to the output stage
11) Issue 1010: Changing Geant4 physics flags 
 

Newly pending:
12) PR 1011:   Allow HepMC3 ROOT input files in ddsim (W. Deconinck)
13) PR 989:     Automatically interpret hepmc3 input files (W. Deconinck)
 

2)    Closed issues and fixed problems
----

1) PR 1006:   Improve readability of magnetic multipole formula (Documentation improvement D.Gangadharan)
2) PR 1005:   examples:OpticalTracker: declare dependency on DDRec (A.Sailer)
 

3) Round table

----
  Markus:     Working on DDDigi
  Alvaro:       NTR

  Andre:        - Multiple user questions answered.
                      - Looking into the question of exciting ions.
                      - Looking into the physics list setup.
                      - Plugin manager extension: show file name of plugins
  Juraj:          Looking into color propagation of detector colors
  Thomas:    Had a look into the edm4hep issue. Chosen solution is to solve the issue "downstream" in the FCC code.
 

4) AOB
----
For LCG stacks: LHCb asked to change default units to G4units.
