#### Applying coupling conditions to the individual domains

The code is stopped as soon as the values of ```avg[bgs][0]``` and ```avg[bgs][1]``` are below the convergence criteria set in the config file.

The displacement field on the structural domain and the velocity field on the flow domain obtained in ```fsi_steady_1.vtu```_and ```fsi_steady_0.vtu``` respectively are shown below:
The displacement field on the structural domain and the velocity field on the flow domain obtained in ```fsi_steady_1.vtu```_and ```fsi_steady_0.vtu``` respectively can be visualized with paraview and are shown below:

Note that the cantilever geometry is stored as the original undeformed geometry and a displacement field. In paraview, the geometry can be deformed to match the flow domain using the 'Warp by Vector' filter.

#### Relaxing the computation

In order to increase the speed of convergence, it is normally a good option to apply a relaxation
