Hi,
now that we can use tensor elements in dolfin through UFL,
what would be the easiest way to extract a row of a tensor
field (Function over a TensorElement) as a vector field?
I think scalar subcomponents can easily be extracted,
but is it possible to piece these together to a vector field?
Something like:

Function v(V);
Function a = A[0];
Function b = A[1];
v[0] = a;
v[0] = b;
