FieldSlicer error

[mncrowe]

Hi,

I've been trying to set up an output writer to save surface fields for a 3D simulation.

From what I've read, the following should work:

simulation.output_writers[:surface_slice_writer] = NetCDFOutputWriter(model, merge(model.tracers, (; KE, p, zeta));
schedule = TimeInterval(1hours),
filename = "eady_turbulence_512_surf",
overwrite_existing = true,
field_slicer = FieldSlicer(k=grid.Nz))

However, I get the error: "UndefVarError: FieldSlicer not defined". Also, printing the output writer gives:

NetCDFOutputWriter scheduled on TimeInterval(12 hours):
├── filepath: ./eady_turbulence_512.nc
├── dimensions: zC(64), zF(65), xC(128), yF(128), xF(128), yC(128), time(0)
├── 5 outputs: (v, w, b, u, zeta)
└── array type: Array{Float64}

which suggests it doesn't have field_slicer as a parameter. I've attached the full code below.

Does anyone know what I'm doing wrong here?

Thanks,

Matt

Please include which version of Oceananigans you are using. I have a feeling that you may be using deprecated syntax ie syntax that does not correspond to the version of Oceananigans you have installed. indices has replaced FieldSlicer quite a while now I think. See, eg,

https://clima.github.io/OceananigansDocumentation/stable/generated/baroclinic_adjustment/#Diagnostics/Output

and

Thanks, version is v0.86.0.Uusing 'indices' fixes this as you say.
