Problem with compressible flow in Star CD 3.26
 
Hi,

I am using star CD for simulating compressible flow.I have two inlet and one outlet. Out of two inlets one is mass inlet while other is pressure inlet. Outlet is pressure outlet. I am not using stagnation or environmental pressure boundary for my problem.

I have defined ULR as given below: for u,v,w: 0.4

p: 0.12

k,e:0.4

T:0.90

I have got residuals below 10 -3. After post processing i found that velocity and pressure contour ok.but at boundary temperature is very high compared to given boundary value. I have problem with temperature convergence.please can anybody suggest me to eliminate temperature problem?
