@article{Guermond1997CalculationOI, title={Calculation of Incompressible Viscous Flows by an Unconditionally Stable Projection FEM}, author={Jean-Luc Guermond and Luigi Quartapelle}, journal={Journal of Computational Physics}, year={1997}, volume={132}, pages={12-33} }

This paper investigates the numerical performance of a finite element implementation of a new incremental fractional-step method to compute steady and unsteady incompressible viscous flows under general boundary conditions and using unstructured meshes. A variational framework is adopted which accommodates two different spaces for representing and approximating the velocity fields calculated respectively in the viscous and inviscid phases of the method, but which leads to a very simple…
