I receive this message in the start of the simulation:
This is a multiphase simulation with a compressible phase. | | Total pressure (used for post-processing or if total pressure | | is specified at a boundary) is calculated using the following | | continuous fluid: fluido | | The frozen assumption is used for all dispersed phases; | | ie, they do not contribute to the total pressure. I have two fluids: fluid ( water liquid) and fluid2 ( water vapour). Does this means that I have to sum the water vapour Total pressure to the one on the CFX-Post (fluid) to get the true total value?

What I think this message is saying is that the total pressure will be calculated for the continuous phase. As the discrete phases can have different velocities, therefore they can theoretically have different total pressures. But different pressures existing at the same point is not physical (in most multiphase model systems anyway), so CFX avoids this by just calculating total pressure on the continuous phase.
