negative force on airfoil
 
I'm getting my total force on the airfoil to be negative.I'am not able to figure out what could be wrong with my mesh and boundary layer.Could it be the boundary layer direction.Also the pressure on the top of airfoil is more than the pressure on the bottom(which is wrong since there is no lift).What could i do to rectify this..
