Computation of the base flow

The file `bfs_tg.bse`

is the output of the base-flow
computation that should be run for a non-dimensional time of t ≥ 300 to ensure that the
solution is steady.

**Task: 2.1** Convert the base flow field file `bfs_tg.bse`

into VTK format to look at the
profile of the base flow. Note the separation at the step-edge and the reattachment
downstream.

The streamwise component of the velocity, u, should look like in figure 2.2.
