Fluent vs post engine calculator ? results
 

Hello

I m using ANSYS 15.0 for some time but i never wanted to know exact forces that i can calculate with FLUENT. But now i do. But there is problem. Anytime i set simulation ( no metter if its simple cube or complete car ), forces that post calculator calculates are absolutely different than the ones that i can read from converged simulation monitor ( from last iteration in which it find convergence ). I m using boolean method from catia so i just import domain and in meshing create named selections and from them i let fluent and post calculate forces. How can they be 20x (estimate) bigger or smaller no metter what i simulate ? i m using symetry which does not effect forces ( i still need to make them doubly using my calculator ) ... so where is problem ? Thank you

Sorry for my english
