this is the udf which i hv written ......but there is error while iterating.

#include "udf.h"

DEFINE_PROPERTY(cell_radial,c,t)
{
real rad_dis;
real a_a;

a_a=1-pow(((1.-C_VOF(c,t))/0.63),(1/3));
rad_dis=(3/5)*pow(a_a,-1);

return rad_dis;
}

Hello, ravindra.
Were you able to solve this problem? I have the exact same problem and I can't write a right UDF for it.
Thanks in advance!
