Hi Foamers
I have a problem with force and force coefficient plotting.
I add this to end of cavity tutorial controlDict file
forces
{
type forces;
functionObjectLibs ("libforces.so"); //Lib to load
patches (fixedWalls); // change to your patch name
rhoInf 1.225; //Reference density for fluid
CofR (0.25 0 0); //Origin for moment calculations
}
forceCoeffs
{
type forceCoeffs;
functionObjectLibs ("libforces.so");
patches (fixedWalls); //change to your patch name
rhoInf 1.225;
CofR (0 0 0);
liftDir (0 1 0);
dragDir (1 0 0);
pitchAxis (0.25 0 0);
magUInf 10.0;
lRef 1;
Aref 1;
}
and I solved it by icoFoam > log
and then when I type " gnuplot forceCoeffs -" I got this message
"forceCoeffs", line 10: warning: Skipping unreadable file "./forceCoeffs/0.0005/forceCoeffs.dat"
"forceCoeffs", line 10: warning: Skipping unreadable file "./forceCoeffs/0.0005/forceCoeffs.dat"
"forceCoeffs", line 10: No data in plot"
I think that I did not calculate force and force coefficient correctly.Can any one help me?
Thanks
