Hi .. in species transport in FLUENT .. for the UDF i need to know the flow variables of the mixture (dry air + water vapor is my species transport mixture) and in certain case I need to know the properties associated with the water vapor only - (partial pressure to say.. or the property values) .. is this possible is FLUENT and how?

I checked the manual for this and it says only for the MULTI PHASE case .. that .. for different domain IDs we can ask the UDF to return values associated with different phases or the mixture as a whole .. is the same possible with Multiple Species ??? plz help
