Dear all,

I am trying to apply UDF to my case, which is 2D vertical axis wind turbine simulation on ANSYS. I imported my UDF file to ANSYS, it works but my turbine is not turning. Where am I doing wrong? Any suggestion about it?
Thank you in advance.

This is my UDF code.

#include "udf.h"

DEFINE_SDOF_PROPERTIES(rotor, prop, dt, time, dtime)
{
prop[SDOF_MASS] = 0.1;
prop[SDOF_IXX] = 0.018;
prop[SDOF_IYY] = 0.018;
prop[SDOF_IZZ] = 0.005;

prop[SDOF_ZERO_TRANS_X] = TRUE;
prop[SDOF_ZERO_TRANS_Y] = TRUE;
prop[SDOF_ZERO_TRANS_Z] = TRUE;

prop[SDOF_ZERO_ROT_X] = TRUE;
prop[SDOF_ZERO_ROT_Y] = TRUE;
prop[SDOF_ZERO_ROT_Z] = FALSE;

printf ("\n Blade updated 6DOF properties");
}

Check your axis in model, may be it is not Z =)

Best regards
