possibility of incorporating knowledge in CFX
 

I wanted to know whether it is possible to incorporate co-relations (say gas hold up corelations,developed empirically or using machine learning tools)in fluent as user defined function or incorporate knowledge into it as to when you expect a certain flow regime change.I will be very grateful if someone who has tried something like this or is aware of this, posts a reply.Is it possible to incorporate a known knowledge into CFX? thank you regards, rakesh
