problems with the stability of results

thank you for your interest ghorrocks. I changed the timestep from 0.1 s (one third of the remaining time of the fluid within the domain as reccommended) to 0.001 s. Doing so, the values of my monitoring points changed from being really chaotic and oscillating to a much more smooth appearance. Again, thank you for your interest. Kind regards from spain

Steady state or transient?
