Hi guys, i can't plot both forces and force coefficients togheter with gnuplot but one for time. When i include only the function object of forces in system directory i can plot forces with gnuplot but if i add the function object of force coefficients, in directory postprocessing i find only force coeff and i can plot only those. What was i wrong?

In controldict i have addes this:
functions
{
#include "forces"
#include "readFields"
#include "forces_coeff"
}
And I have defined those funcions object:

forces
{
type forces;

functionObjectLibs ( "libforces.so" );

outputControl timeStep;
timeInterval 1;

log yes;

patches ( "TRAILING_EDGE.*" "SUCTION_SIDE.*" "PRESSURE_SIDE.*" );
pName p;
UName U;
rhoName rhoInf; // Indicates incompressible
log true;
rhoInf 1; // Redundant for incompressible

CofR (0 0 0); // Rotation around centre line of propeller
pitchAxis (0 0 1);
}

forces
{
type forceCoeffs;

functionObjectLibs ( "libforces.so" );

outputControl timeStep;
timeInterval 1;

log yes;

patches ( "TRAILING_EDGE" "SUCTION_SIDE" "PRESSURE_SIDE" );
pName p;
UName U;
rhoName rhoInf;
rhoInf 1;
log true;
CofR (0 0 0);
liftDir (-0.1736 0.9848 0);
dragDir (0.9848 0.1736 0);
pitchAxis (0 0 1);
magUInf 25.75;
lRef 0.5459;
Aref 0.5459;
}

And also readfields:

readFields
{
// Where to load it from (if not already in solver)
functionObjectLibs ("libfieldFunctionObjects.so");

type readFields;
fields (p U k omega);
}

Do you individuate any errors which impede contemporary writing of both forces and forces coeff in postprocessing?

names for both function objects in your controlDict are the same. Change one of them and it should work.
