Dear all,
I tried to add a Lagrange multiplier to the miscellaneous_ex14, but it
doesn't change anything. Maybe it is a stupid error I have, but I have
no clue what exactly to change.
What I expect to do is to add a Lagrange multiplier that sets the
solution to 0 at all elements at radius >=4 units.
The changes I applied can be found at

Can someone please help me, what I am doing wrong? According to the
example systems_of_equations_3 and _5, it doesn't look actually too
complicated.
Many thanks in advance,
Hubert
