a problem in drag coefficient calculating
I want to calculate drag coefficient on each walls of a cube with unit dimension which is located in a flat plate. The inlet velocity components are (1,0,0) and the density of fluid is 0.1; I add the following code to controlDict :
functionObjectLibs ( "libforces.so" );
CofR (0 0 0 );
liftDir ( 0 0 0 );
dragDir ( 1 0 0 );
pitchAxis ( 0 0 0 );
But the result isn't true. Would you tell me the mistake?
Do you use OpenFoam software for your simulation?
