What Actually Happened
List of requirements for a future ACME coupler.
Regridding (aka interpolation aka mapping) needs:
vector fields interpolated correctly on a sphere
staggered grids handled natively without interpolation to cell centers
higher-order methods choosable on a per-field basis
interpolate gradient AND field for some fields
possibly iterative to optimize some fields
Allowing for dynamic grids
Some algorithmic work necessary such as vector fields in spherical coordinates
AMR support? not needed soon. Bicycles has support
support for components that share an interface, 3D for ice-sheet-ocean
Time interpolation
option for implicitness
get away from lagging output
understand/control time integration error
Coupling design
Allow pair wise coupling between components if they want (same grid)
coupler functionality callable from other models. For atm/dyn physics for example
coupling of models with 3D-partial overlapping interfaces.
more runtime configuration and runtime loadbalancing
handle dynamic domains: wetting and drying of land and ocean from sea-level rise.
Go away from flexible coupler that allows any atmosphere, any ocean. Specific coupling for ACME components.
Force models to agree on boundaries, decomposition to lower workload of coupler.
