lectures?
Incidentally, do you have any ideas on how to solve the singularity of the
mass matrix in this vector-valued problem?
Bests,
; calculations. I prefer to be on the safe side…

Out of curiosity, what is the reason to use (2*fe_degree + 1)? Checking
step-8, I notice that there a quadrature degree one larger than the
