Hi Nathan,
Yup, I agree with your assessment -- there's an edge effect. You need
one more thing to get the derivative field working; you need to tell
yt to give you an extra zone in each direction. You can do that by
changing your decorator for the derived field to:
@derived_field(name = "GravGradientX", validators = [ValidateSpatial(1)])
I don't believe you need any additional changes inside the source
code. Let us know if that fixes it!
