interoperability
Interoperability…
  • Different applications generally have different needs/requirements
    • Model resolution / stratigraphic details
    • Type of discretization
    • Discontinuous vs continuous units
  • Multiple softwares may be involved
    • Compatibility problem
    • “Software interplay”:
      • Time-consuming operations
      • Integration of errors
a streamlined process
A streamlined process…
  • The Geologic Framework Model is created first
  • 3D grids are generated/updated semi-automatically
    • A series of actions is executed by a user
    • The “history” is saved (text file)
    • This file is updated and run every time the same task (e.g. building a new discretization) is needed
      • Run time… just enough to go get a coffee…
