Comments

 Two students could not prepare the required figures properly and the discussion about the simulation results is not enough

 Several students could not have the frequency of drag force correctly, so they calculate wrong Strouhal number

 Some of students put the wrong answer for the drag force of each component of Ahmed body

 Also, a few of students extracted inappropriate force value from the experiment figure to compare with simulation results
