Hello,
Currently, if any elements are restricted to a Measure,
_auto_select_representation() will default to 'quadrature'.
However, this doesn't work for the following form with an EnrichedElement:
P1 = VectorElement("Lagrange", triangle, 1)
element = P1 + P1[ds]
f = Coefficient(element)
M = inner(f, f)*dx
It is also worth noting that the list of unique elements for this form is just
one element:
'<Vector<2 x CG1> + <Vector<2 x CG1>>|_{ds0}>'
I was wondering the list of unique elements from UFL.FormData should also
contain:
'CG1', 'Vector<2 x CG1>' and '<Vector<2 x CG1>>|_{ds0}'?
The question is if the fix for _auto_select_representation() should be
implemented in FFC by
handling EnrichedElements explicitly or in UFL by adding elements from
EnrichedElement to the
list of unique elements.
