The main documentation is in the subdirectories.

Setup

source either key4hep stable

source /cvmfs/sw.hsf.org/key4hep/setup.sh

or source key4hep nightlies

source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh
git clone https://github.com/key4hep/CLDConfig.git

cd CLDConfig/CLDConfig/

Simulation

ddsim --compactFile $K4GEO/FCCee/CLD/compact/CLD_o2_v06/CLD_o2_v06.xml \
            --inputFiles ee_Zmumu_91.hepmc \
            --numberOfEvents 10000 --steeringFile fcc_steer.py \
            --outputFile Zmumu_91_10000ev_SIM_edm4hep.root

Simulation with ParticleGun

ddsim --compactFile $K4GEO/FCCee/CLD/compact/CLD_o2_v06/CLD_o2_v06.xml \
      --outputFile outputSIM.edm4hep.root \
      --steeringFile cld_steer.py \
      --random.seed 0123456789 \
      --enableGun \
      --gun.particle mu- \
      --gun.energy "1*GeV" \
      --gun.distribution uniform \
      --gun.thetaMin "89*deg" \
      --gun.thetaMax "89*deg" \
      --crossingAngleBoost 0 \

Note

simulation output file format must be .edm4hep.root or .slcio
