#### 2.1 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 5.
