I second Wolfgang comment on the fact that Q1Q1 is not difficult to implement. You can also scale it to arbitrary Qn-Qn elements if you are interested in higher order. We have implemented such an approach in our code based on dealii ( https://github.com/lethe-cfd/lethe) Q1Q1 is already very

Hi everyone! I am trying to implement the stabilizations presented in a paper by Bochev et al. [2006], which you may find here: https://pdfs.semanticscholar.org/47be/4e317d4dcbbf1b70c781394e49c1dbf7e538.pdf This one is parameter free, and they present local projections for both Q1Q1 and Q1Q0
