Total Pressure only increases

I made a simple intercooler simulation.
The total pressure of inlet and outlet of the core (actually without porous medium) only increases and didn't get constant. But pressure drop is nearly constant. K-Omega, steady - good poly mesh. Temperatures etc. are constant, only pressure fools me. The core is connected via 2 interfaces, total pressure report runs on the interfaces. Somebody an idea? unsteady effects? faults in the report because of the interface? |

Argh.. I think I found the error. The "old" ccm bug with interfaces.
I tried the other side of the interface and there the pressure seems to be constant - but I will test it. |

Problem solved, used coupled flow... don't know why I used the coupled but with segregated all is fine.
