Could your problem come from the support of your function spaces?
They are defined on "Domain" and "DomainC".
But your formulation (to compute the boundary condition) is defined on
By going really quickly through your .pro file, I have the feeling that
"Infinity" is not in "Domain" or "DomainC".
Is it possible?
That would explain your problem :-).
I hope this will help.
