During initialization the message appears: "Pressure information is not available at the boundaries", although I use a pressure outlet.

Case: Flowsimulation in a nozzle with a rod:

 

(inlet on the left side)

Settings:

• pressure-based
• steady
• laminar
• material: at least constant density (1010 kg/m^3) and viscosity (1000 kg/ms)
• without energy equation
• velocity inlet; v = 0,01364 m/s
• pressure outlet: 0 Pa
• stationary walls (no slip)
• reference values: from inlet
• solution methods: default
• solution controls: default

residuals:

Are the residuals low enough? It does not seem converged to me..

Why does fluent say: "pressure information is not available at the boundaries"?

I started with a simple case and wanted to expand it little by little, but it does not seem to run properly yet.

Does anyone have an idea?

Thanks so far!!

There are some warning at the initialisation stage depending on what boundary conditions are set. If you plot contours on the domain, and a few planes how does the flow field look?

Note, I can't read the residual plot so don't know what sort of values you're seeing.
