Public bug reported:


interpolate allows interpolation to/from spaces of different value dimensions. This is error prone. Should add check (unless someone considers it to be a feature.)

from dolfin import *

mesh = UnitSquare(2, 2)
V = VectorFunctionSpace(mesh, "CG", 1)
f = Expression("1.0")
w = interpolate(f, V)

** Affects: dolfin
     Importance: Undecided
         Status: New

** Changed in: dolfin
    Milestone: None => 0.9.11
