Hi,

I get the following warining in the beginning of the simulation:

The pressure level was not set by any of the boundary conditions. Zero relative pressure will be set at the first finite volume equation in domain "tuborg1".

All boundary are defined as inlet and outlet and a background pressure has been defined to 1.01E5.

Does it has any influence on the solution ?

Regards

Peter

If you are using an Ideal Gas this will influence the solution since some of the fluid properties depend on the absolute pressure level. In this case, you should try to change one of your boundary conditions so that the relative pressure is set somewhere, e.g. change a velocity inlet to a velocity and pressure inlet. Mike
