Default very urgent pleasade:Cl and Cd values for airfoil

Hi I am doing a simple 2D analysis to find Cl and Cd values for an airfoil. 1. Where are the Cl values listed in the solution or how is it setup. 2.Where are the Cd values listed in the solution or how is it setup. 3. I think it's necessary to use one of the turbulance models to get a viscid solution. Now when I pick any of the models e.g.Spalart-Allmarass mdoel, do I need to change any of the parameters and constants on the page or all remain unchanged. 4. Since Cd values are usually quite small comapred to Cl, is their a way to change the scale on the graphs.

Urgent help is appreciated

Cd & Cl can be obtained from

solve -> monitor -> forces.

in forces select the required data & say ok.

Thanks a lot Sir. Any ideas on second part of my questio i.e. changing scale for drag calculation and which model to select for turbulence to get right values for drag. Best regards
