  • Simulation Volume for Hercules
  • Projection used by AWP
  • Project used by Hercules
  • Number and location of sites used for ground motion comparison
  • La Habra Point Source parameters
  • Currently available code capabilities in GPU codes
    • small scale heterogeneities
    • FDQ
    • Plasticity
    • dynamic rupture source
  • V and V exercise stages - need to be reviiewed and approved
