DOLFIN

product of more than two spaces

Asked by JG

How does one compute with trial/test spaces which are products of more than two spaces? The following simple code gives me the error message "ValueError: need more than 2 values to unpack". What is the supported way to do this? (I need to compute with a space with four component spaces.) Thanks, --Jay

from dolfin import *
mesh = UnitSquare(2,2)
W = FunctionSpace(mesh, "CG", 1)
S = W*W*W
(u,v,w) = TrialFunctions(S)

S = MixedFunctionSpace([W, W, W])
