You can find the Gnuid paper in the early view of Communications in Numerical Methods in Engineering. *An adaptive mesh refinement solver for large-scale simulation of biological flows* Lorenzo Botti, Marina Piccinelli, Bogdan Ene-Iordache, Andrea Remuzzi, Luca Antiga
The solver is based on a velocity correction scheme, it works with P2-P1 elements, and it is not stabilized. Adding some kind of stabilization to the advection-diffusion equation I think it could be used in aorta too. In its current state the restriction on the time step size for high (>1000) Reynolds number is quite severe. I'm developing a DG INS solver for advection dominated flows. You will find it at www.vmtk.org as soon as it is ready for release.
