Oceananigans v0.26.0

Diff since v0.25.2

Some breaking changes:

• Function signatures for boundary condition functions and forcing functions have been simplified.
• The model.parameters field has been nuked in favor of more local "parameters" functionality. ParameterizedForcing and ParameterizedBoundaryCondition convenience types and functions have been added

The new forcing function signature is

F(i, j, k, grid, clock, state)

while the new boundary condition function signature is

bc(i, j, grid, clock, state)

where i, j are indices along the boundary.

state is a NamedTuple with fields velocities, tracers, and diffusivities, each corresponding to an OffsetArray that references the data associated with each field.
