GENIE Main

Philosophy

Central location for shared stuff. 'Linchpin' for coupling together model components.

All values exchanged between components for the coupling process should pass through genie-main. No 'secret passages' or 'trap doors', which can be a sideffect of using common blocks.

Avoid duplication. Maintain a clear, hierarchical relationship. This significantly enhances clarity and correspondingly the process of extending and improving the model.

Source Code

• genie_control.f90
  • flags to control the component coupling

• genie_global.f90
  • any common variables (i.e. those used during coupling)

• genie.F
  • the overall coupling logic and time loop: do this, then that, then the other, if, then, else.

argument passing.
