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.
