Hi all!
I got used to working with a Field of vectors such as:

Field<vector> someVectorField(LengthOfField, vector::zero);

Now I need 5 "coordinates so instead of a vector field i would use a field of fields. Didn't find anything on the topic, so I just tried to approach it logically:

Field<Field<scalar>> someFieldField(LengthOfOuterField, (LengthOfInnerField, 0.0);

Unfortunately this does not work. I can however define it as such:

Field<Field<scalar> > someFieldField[LengthOfOuterField][LengthOfInnerField];

but I have no idea how to declare it afterwards. Tried = 0 or = {0} and such. Also someFieldField[0][0] = someScalar; does not work since seemingly the left hand side is still a field and not a scalar...

I appreciate every bit of help. Thx in advance!
