Question Write profile to set boundary conditions

MiraLisa is on a distinguished road
I'm working with a 3D channel flow and want to simulate the jet flow coming out of the channel. In order to do this I have first simulated a channel flow, with a pressure outlet at the end of the channel.

Now I want to import the results from the pressure outlet and set as boundary conditions for the inlet in another geometry (shaped like a box) in order to see the jet behaviour. To do this I used write --> profile and chose values for the channel outlet.

I have managed to import the velocities in x,y,z and k & epsilon for the turbulence model. However i cannot find a way to import the volume of fraction for water, which is needed when setting the boundary conditions for the inlet. Is there a way to do this? Or do I need to define a "udf" for this? I would rather not do a udf, because i'm not sure how to do it...

I am grateful for any help I can get.
