Hey victorlin,

Thanks for posting on the forum.

As the error clearly states, a pressure boundary condition is necessary for continuity to be obeyed. Use a pressure outlet boundary condition for your outlet instead of a velocity outlet as mentioned in this part of the tutorial you are following.

Best,
