Michael,
   You need to connect the pressure as well. It is surprising that you 
always get the warning. I would understand if you get that warning for 
some timesteps (maybe even enough timesteps to go over the allowable 
number of warnings in a simulation. However, if you get that warning at 
every single timestep, there might be something else wrong.
Regards,
  David
