Hi mates,

Hi mates,
I'm making a simulation of an aortic valve,it is a fluid-structure interaction between the fluid and this valve.
The valve has 1 degree of freedom that is the rotation, so i used this udf:

#include "udf.h"
DEFINE_SDOF_PROPERTIES(valve, prop, dt, time, dtime)
{
prop[SDOF_MASS] = 0.001;
prop[SDOF_IZZ] = 0.00833;
prop[SDOF_ZERO_TRANS_X] = TRUE ;
prop[SDOF_ZERO_TRANS_Y] = TRUE ;
prop[SDOF_ZERO_TRANS_Z] = TRUE ;
prop[SDOF_ZERO_ROT_Y] = TRUE ;
prop[SDOF_ZERO_ROT_Z] = TRUE ;
printf ("\n2d_valve: Updated 6DOF properties");
}

what i missed ?
