Default Monitor points in multiphase flow

I am trying to create an expression for an additional variable monitor point.

The expression I have is: volumeInt(Radiation)@Fluid

This has been working fine for single phase fluid flow but I would now like to model multiphase and was wondering how to apply this to expression to a specific fluid.

Probably simple, I just can't think how to do it.

Thanks,
Stuart

Take a water-air system for example, if u want to monitor the air volume fraction mixing in the tank, u can use volumeAve(air.vf)@Tank.
Similarly, u can use volumeInt(Phase A.Radiation)@REGION in your case.

Thanks for your reply, however I am still having problems with it.

When I enter the expression as you suggested, i.e. volumeInt(Air.Radiation)@Fluid I receive a different error message : The additional variable 'Air.Radiation' referenced in parameter 'Expression Value' in object '/FLOW:Flow Analysis 1/OUTPUT CONTROL/MONITOR OBJECTS/MONITOR POINT:Radiation does not exist in Domain 'Fluid'.
