Hi,

Below are some relevant refs for the docs/cite page: http://fenicsproject.org/citing/

Two old ones for DOLFIN and FEniCS, and then representative papers for key aspects of DOLFIN/Unicorn such as parallel adaptive methods, adaptive LES turbulence simulation, unified continuum fsi:

* N.Jansson, J.Jansson and J.Hoffman, Adaptive finite element computational fluid dynamics for large scale massively parallel computing, SIAM J. Sci. Comput., accepted.

* J.Hoffman, J.Jansson, M.Stöckli, Unified continuum modeling of fluid-structure interaction, Mathematical Models and Methods in Applied Sciences, Vol.21(3), pp.491-513, 2011.

*J. Hoffman and C. Johnson, Computational Turbulent Incompressible Flow: Applied Mathematics Body and Soul Vol 4, Springer-Verlag Publishing, 2007.

* T. Dupont, J. Hoffman, C. Johnson, R. Kirby, M. Larson, A. Logg, R. Scott, The FEniCS project, Chalmers Finite Element Center, Preprint 2003-21, 2003.
