CHOICE OF ADVECVTION SCHEME in the cfx
 
Dear sir,

I am solving a centrifugal fan problem. As i am going for the solver control. I am getting three options for the advection scheme as given below

1. high resolution (blend factor varies between 0.0 to 1.0)
2. upwind ( blend factor = 0.0 )
3 specified blend factor having default value 1.0

As blend factor is 1.0 Which scheme is applied ?
1) second order upwind, or
2) Second order central differencing scheme

Blend factor=1.0 means pure second order upwind.
