### Theory

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:

### Numerical approach

All numerical details here.

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.
