Incompressible Fluid Application
ADVERTISMENT STYLE no numerical details!!!
The aim of this application is to solve the well known set of Navier-Stokes equations. The problem suffers from severe locking and/or instability using linear FEM.
Different approaches could be chosen to solve this problem. Fractional step, Subgrid scale stabilization, GLS are among the others.
Some references to these methods are:

This is a part quite open, depending on the application we are considering.
Every physical problem is solved defining many different ingredients. Try to be quite schematic.
