Question about time step error
 
Hi,
i'm solving a problem about incomprissible fluid and i want to ask a simple question.

when simulation starts in p iterations i read
time step continuity errors : sum local = 0.061115794085, global = -0.0048278919849, cumulative = -38.1523156313

what it means each error?? how much important to assess the right convergence solution??
why does it show only in p?

Thanks to all!!
