SetGrid rule error

[remylegoff]

I'm now using SetGrid to make a grid wide operation and an error occur. Even for a basic test operation like the example

using DynamicGrids
rule = SetGrid{:a,:b}() do a, b
    b .= a
end

the error is
MethodError: no method matching (::var"#53#54")(::DynamicGrids.RuleData{…}, ::DimArray{…}, ::DimArray{…})

is it due to DimArray use ?

No, you are just missing the first argument before a

DynamicGrids passes you the data object in case you need the timestep or aux data etc.

But try not to use SetGrid unless you have to, you lose a lot of optimisations you get in a regular rule, and you can't chain operations on GPU.
