Pressure settings

Pressure settings, too, are the same for the steady-state and transient case. The total pressure (sum of static pressure and specific kinetic energy) is set to fixed value on inlet. On outlet we use the fixed mean value; on average the pressure is supposed to have some reference value, but it can fluctuate. Otherwise we use standard boundary conditions.
