Particle tracking in multiphase flow

Hi. I'm modelling a multiphase flow problem with particle tracking. The problem consists on a channel or launder where ther is water flowing in the bottom, and air on top (a typical open channel). For the inlet boundary condition I had to use a step function in order to say that water enters on the bottom and air on top. The thing is, now I have to inject particles with the water.
I get an error that the problem is not supported in CFX11, because I have two eulerian phases, air and water:
"In domain 'Domain 1': Particle tracking problems with more than one continuous eulerian phase are not supported."
What can I do? I've seen cases of air and water with particles. Does CFX 12 support this?

You have to set the particles as a disperse/discrete phase. You cannot have particles as a continuous phase.

as gleen said, also read this Particle injection boundary condition
Top 4 tips
1. Knowledge is everything and Ignorance is dangerous.
2. Understand your limitations and try to eliminate them.
3. Get yerself a bike and hoon the chuffer. You will soon learn why dogs like to hang their heads out the car window.
4. Please before asking any questions on how to run simulations in CFX, go though all the tutorials

So just switching to morphology "Dispersed solid" will fix the issue ?
