CFX definitions of Rotating Variables: Confusing!
 
In CFX documentation, it is mentioned that p(stat) is "relative" static pressure. Why is it relative? As far I know, we have only one static pressure.

I am working on rotating domains. Bit confused with various parameters, hoping anyoine can clarify!

Where does one use variables like Rotating frame total temperature, rotating frame total pressure etc ? Are these the Total Pressure and Total Temperature which we see in the variable list in POST.

As far as I know, we use relative values only like relative frame total temperature, relative frame total pressure.etc.

Again, if I get back to static pressure, it is said in documentation that "Pressure" defined in CFX is the modified pressure for k-e model. If I use SST model, then how does the definition of "Pressure" change and what is Absolute pressure then?

Thanks

Prakash
