PIC (Poisson) Discharge

  • Test different PrecondType options for PETSC

    • 1,2,3,10
    • 4 and 11 currently fail
  • RF discharge between two electrodes with Helium

    • Ionization of background gas
  • Secondary electron emission at x-direction boundaries

    • only happens rarely for this setup (but code coverage of SEE modules is still performed)
    • Emission model: SEE-I (bombarding electrons are removed, Argon ions on different materials is considered for secondary e- emission with 0.13 probability) by Depla2009
  • The results (total number of particles) are shown in n_parts_total.jpg for MPI=1,...,10

  • Count the number of electrons that impact on the left boundary and output to SurfaceAnalyze.csv (compare the last line with a reference)

      CalcBoundaryParticleOutput = T 
    
  • using rounded values for all particle masses

    • otherwise fails when using CORE_SPLIT and MPI=5 due to "Message: CODE_ANALYZE: DSMC_Chemistry is not energy conserving for chemical reaction: 1"
    • not that rel. Energy difference : -1.18806002360921E-012
  • Output of temporal derivative of the electric field

      CalcElectricTimeDerivative =T
    
  • Output of min/amax/average electron energy (eV) in each cell

      CalcElectronEnergy = T
    
  • Test both load balances schemes. Load balance via hdf5 I/O and via direct MPI communication without I/O

      UseH5IOLoadBalance = T,F
