So I thought about that: this is due of calling of material property methods where the temperature calls might be static or total. Background is the isentropic stagnation conditions
H(Ttot,Ptot)=H(T,P)+Kinetic Energy and Total entropy is set equal to equal entropy. Usign a numerical method (Newton's Raphson) we backup the quantity required. And here where you will observe calls to UDRGM with total conditions as arguments. In your example these occur at the pressure inlet.
