Why does my lift force look like this?

  I am running a simulation of two airfoils on top of each other and I cant get my lift force or scaled residulas to converge. When I change the outlet to only half of the back wall it works but when the outlet is the entire wall it doesn't work. I have na inlet velocity of 13 m/s in the x direction only.

  Please post some contours etc to show what the flow is doing. You can't rely on just a single line to diagnose flow.
