Summary of the results obtained for six simulations with Σa = 100 kg m−2.

Σa = 100 kg m−2 S t = 0.01 S t = 0.02 S t = 0.05 S t = 0.075 S t = 0.1 S t = 0.2

Notes. “Time of PB formation” is the time at which the pressure maximum appears. All these simulations lead to the formation of a pressure bump, but at different times.
