菜鸟请教：简单的UDF程序通过编译，但初始化出错，大家能帮我看看，查出错误吗

monkeying

#include "udf.h"
#include "mem.h"
#define diam 2.0e-4

DEFINE_PROFILE(x_inertial,t,i)
{
  real Re,mu;      /* variable declarations */
  cell_t c;
//C_CENTROID(x,c,t);
  real vx=C_U(c,t);  /*x-velocity*/
  real r=C_R(c,t);   /*density*/
   mu=C_MU_L(c,t);    /*层流viscosity*/
// mu=7.95e-06;
  Re=vx*r*diam/mu;
  begin_f_loop(c,t)
  {
          if (Re<5)
                   F_PROFILE(c,t,i)=0;
          else
                  F_PROFILE(c,t,i)=5.84e4;
  }
  end_f_loop(c,t)
}

点击init报错
