I said the operating density needs to be that of the surrounding fluid, ie whatever the backflow condition is. Not what's leaving the domain. So, air at ambient conditions is around 1.182345kg/m3. I suspect you're seeing the effect of the hydrostatic pressure if you set the outlet as a uniform pressure. 

If you want to check the results you want the Solve part in Workbench. You've just found one of the many reasons we tend not to use WB! Note, there are parametric tools in Fluent standalone too, that may make life a little easier.Â
