[firedrake] Difference between u.split() and split(u)

[Buesing, Henrik]

Dear all,

I have a multi-physics problem and u is my unknown. I was wondering what the difference between

u.split() and split(u)

is.

It seems that the Jacobian is only right, when I use split(u) and then further use this in subroutines. If I use u.split() my Jacobian is zero...

Thank you!

Henrik
