The only thing I changed a bit is the integration from quadratic to

In
https://github.com/tjhei/cracks/blob/master/cracks.cc
line 982,
you need to change the "degree", but it should be already "1".
And the quadrature formula - what you mentioned above - should be
sufficiently high, "2" should do the job.
Best Thomas
alone is enough for linear shape functions. You also had
face_quadrature_formula or this Lobatto integration.
Would you be so kind and explain what lines I have to change in order
to obtain linear shape functions and not quadratic like set in the
original version?
How many changes and the code would help a lot.
Just to be sure I did it correct.
Thank you.
Best,
Seyed Ali
