Diff since v0.26.0

Breaking changes:

• in FieldBoundaryConditions(grid, location), the argument location is now be a 3-tuple of uninstantiated types, eg: (Face, Cell, Cell) for a field at the location of the u-velocity field. Previously, location was a 3-tuple of instantiated types.

Release notes:

• has_velocities was fixed so that show works for models with no tracers
• BoundaryFunction can now have parameters: use BoundaryFunction(func, parameters) if func(ξ, ζ, t, parameters) takes a final argument parameters. (parameters=nothing by default.)
• four new wrapper functions were defined for specifying 'simple' boundary condition functions:
  1. TracerBoundaryCondition
  2. UVelocityBoundaryCondition
  3. VVelocityBoundaryCondition
  4. WVelocityBoundaryCondition
• All four functions take three (optionally four) arguments: (bctype, boundary, func, [parameters=nothing]), where bctype is Value, Gradient, or Flux and boundary is :x, :y, or :z. If parameters=nothing, func(ξ, ζ, t) is a function of the on-boundary coordinates (ξ, ζ) and time t. If parameters is set, it is passed to func(ξ, ζ, t, parameters).

Closed issues:

• API divergence for abstract operations versus boundary conditions (#659)
• "show" method throws an error for models with no tracers (#700)

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.
