Hi,

I am trying to use Index() in mixed elements in FFC. But it always gives me
an error. I could not find an example of this type.

Does Index() work for mixed elements?

Here is peace of my code:

...
TH = scalar + vector + scalar

(v1,v2,v3) = TestFunctions(TH)
(u1, u2, u3) = TrialFunctions(TH)
...
i = Index();
j = Index();
...
a = v2[i]*u1[i]*dx
...

It give the error:

  a = v2[i]*u2[i]*dx
TypeError: object cannot be interpreted as an index
