problem in calculating force
 
1 Attachment(s)
hi guys I am working on across wind forces on chimney using ansys fluent. after analysing i tried to calculate force along a line but got an error . warning msg is attached here please help me with this.

What force are you trying to access and have you saved this variable for CFD-Post to access?

I jus made a line on the surface of chimney and tried to calculate force perpendicular to direction of flow on that line

I want to calculate force and moment (+Z)perpendicular to flow direction (+X).do you know any other method from which I can get desired results

Did you want to get the lift up force and moment by the wind induction?

yes I want lift up force and moment

What model (DPM or VOF) to simulate the pollutant dispersion?

I'm using vof model. no slip condition for chimney wall and slip condition with no shear stress component for atmosphere boundary
