Dear S. A. Mohseni,
the Gauss points are assigned in that program as always in deal.II:
QGauss<dim> quadrature_formula(degree + 2);
and in the argument, you can change to whatever number you want:
QGauss<dim> quadrature_formula(n);
with n=1 or n=2 or n = 3 for instance.
Best regards,
Thomas W.

Dear Timo Heister and Thomas Wick,
I am trying to run your phase-field crack propagation example, namely
the single edge notched tension test, with less than 9 Gauss points.
Hence, the fe variable is initialized using FE_Q<dim>(degree) where
degree cannot be 0. This means degree should always be >1 here in
order to make things work, but how can one compute the examples with 1
or 4 Gauss points? Is the code not suited for what I am trying to
achieve or where are the parts I have to change in order to make it
work for less integration points. To be honest, I don't even see the
point of having 9 integration points for a 4-noded quadrilateral or am
I overseeing something?
Thank you in advance.
Kind regards,
S. A. Mohseni
