Hello everyone,

I need to plot the friction coefficient using icoFoam solver on a flat plate.

I tried to add the following lines at the end of /system/controlDict, but an error appears when calling "icoFoam" :

functions
(
forces
{
type forces;
functionObjectLibs ("libforces.so");
patches (wall);
rhoInf 1000;
CofR (0 0 0);
}
forceCoeffs
{
type forceCoeffs;
functionObjectLibs ("libforces.so");
patches (wall);
rhoInf 1000;
CofR (0 0 0);
liftDir (0 1 0);
dragDir (1 0 0);
pitchAxis (0 0 0);
magUInf 0.13;
lRef 1;
Aref 1;
}
);



The error :
Create time

Create mesh for time = 0

Reading transportProperties

Reading field p

Reading field U

Reading/calculating face flux field phi

Courant Number mean: 0 max: 0.052

Starting time loop

file: ::functions::forces from line 59 to line 63.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 388.

Can someone help me with this problem please ?
(Maybe there is another way to output the friction coefficient ?)

Thanks
