Force Force-coeffs 3D simulation
 

Hi all,

I'm doing a 3D simulation on Vertical Axis Wind Turbine. I need to calculate the force on surface. I attached the following lines to my controlDict file.


force
{
type forces;
functionObjectLibs ("libforces.so"); //Lib to load
patches (blades); // change to your patch name
rhoName rhoInf;
rhoInf 1.225; //Reference density for fluid
CofR (0 0 0); //Origin for moment calculations
outputControl timeStep;
outputInterval 1;
}
forceCoeffs
{
// rhoInf - reference density
// CofR - Centre of rotation
// dragDir - Direction of drag coefficient
// liftDir - Direction of lift coefficient
// pitchAxis - Pitching moment axis
// magUinf - free stream velocity magnitude
// lRef - reference length
// Aref - reference area
type forceCoeffs;
functionObjectLibs ("libforces.so");
patches (blades);
rhoName rhoInf;
rhoInf 1.225;
CofR (0 0 1);
liftDir (0 1 0);
dragDir (1 0 0);
pitchAxis (1 0 0);
magUInf 6;
lRef 1;
Aref 1;

outputControl timeStep;
outputInterval 1;
}


If the model is 2D no errors appear on the screen, but when I run a 3D simulation appear the following error:

3d VAWT
 

Hi herman, i hope that you are well
i have some question a bout 3d VAWT. i can simulate 2d VAWT with 3 bldes with GGI interface successfully; and now i wanna simulate 3 dimentional of it. would you guide me how perform it? would you send me any documention a bout 3d simulation. my experience a bout 3d dimention in OpenFOAMis very low.
