Skin friction in fluent is wrong

hi,
I am running a simulation for low reynolds number aerofoil flow. I used the k omega sst model with great effect. only problem is the coefficient of skin friction plot does not make sense. I should have negative values of skin friction but it seems that the lowest value of coefficient of skin friction is 0. Can any CFD or Fluent expert tell me where i might possibly make a mistake? Thanks .. appreciate all the help i can get |

hi rashid,
thanks for pointing to that discussion . unfortunately it didnt help me. i cant seem to get negative skin friction on my plots despite having reversed flow appear when i looked at the velocity vectors in the immediate vicinity of the aerofoil surface |
