DD4hep meeting 11/03/2021
-------------------------

A.Sailer, C.Vuosalo, F.Gaede, G.Hugo, M.Frank, M.Petric
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  Coverity error in the Evaluator (to be verified by C.Jones)
       Carl will forward the screenshot to Chris.
1.3  Pending issue in CMS when running Geant4: random number sequences
       differ between builds, runs. Cause unknown, to be investigated.

2)   Closed issues and fixed problems
2.1 CMS issue: If identical containers with children are attached at different
       hierarchical levels, the children are placed multiple times.
       Confirmed by Gabrielle.

3) Round table
   Markus:    Checking Coverity scans
   Andre:       -
   Marko:      Tried to understand the tube issue. May be related to the
                     conversion from radians to degrees and back.
                     Pull request to minimize link dependencies.
   Carl:          -
   Frank:       Small PR for material budget utility to use pseudo rapidity.
   Gabrielle:  -

5) AOB
CHEP21 paper was submitted.

Next meeting in 2 weeks: 25/03/2021
