Performing Simulation of CRM and getting abnormal results of Cl and Cd
 

Hi everyone,
I am performing the simulation of NASA CRM using ANSYS Fluent 14.0, I have created an unstructured mesh using ICEM CFD. I have few questions..
1. I don't know why i m getting abnormal values of Cl and Cd..:rolleyes:?
2. Can anyone tell me how to set the reference values..?

May be i have put in the wrong reference values.

The values that i am using are
Area: 4130 ft^2
Length: 1190 ft

I shall b very thankful for your help.

some more details and what values you are getting of lift and drag. some pics of mesh and geometry.

What does mean by CRM?

Thank your very much for this quick response.
I have attached the files of geometry, mesh and convergence history plots of Cd and Cl.
The current values for Cl = -1.0880e+01
Cd = 2.3813e+01

what is CRM?

CRM is abbreviation for Common Research Model.. I had mentioned it in the image of model.
Its airplane DLR- F6 geometry..
