Hi,

I am using simpleFoam (of v2.1.1). I am trying to find where the forces are applied and have been outputing the forces and moments using the following in the controlDict:

functions
(
forces
{
type forces;
functionObjectLibs ( "libforces.so" );
outputControl timeStep;
outputInterval 1;
patches ( "Volume_0_Wheel-1" "Volume_0_Wheel-2" "Volume_0_Wheel-3" "Volume_0_Wheel-4" "Volume_0_Car" );
rhoName rhoInf;
rhoInf 1.205;
pName p;
UName U;
log true;
CofR (0.0 0.0 0.0);
}
);

It worked great and I got all the outputs in the forces\0\forces.dat file:

# Time forces( pressure, viscous ) moment( pressure, viscous )
997 ( ( ( -25.6521 1575.07 -2489 ) ( 0.0440792 73.7995 8.74441 ) ) ( ( -5215.72 15.0189 86.2846 ) ( -15.0971 -0.0198099 -0.124274 ) ) )
998 ( ( ( -25.6488 1575.07 -2488.99 ) ( 0.0442406 73.8003 8.74387 ) ) ( ( -5215.69 15.0191 86.2908 ) ( -15.0984 -0.0198765 -0.124476 ) ) )
999 ( ( ( -25.6506 1575.07 -2489.01 ) ( 0.0442343 73.8004 8.74362 ) ) ( ( -5215.72 15.0171 86.289 ) ( -15.0978 -0.02023 -0.124946 ) ) )

My problem is that I can't work out how to derive the x,y,z coordinates where the forces are applied to obtain the moment. I have been struggling for a couple of hours and have to admit that geometry is one of my many weak points... Any help would be appreciated.

Thanks in advance
Julien
