看帮助里的例子用到这条语句SET_DEFORMING_THREAD_FLAG(THREAD_T0(tf));
这个是宏吗，它的用法是什么，最关键的是在哪里找到它的用法啊？我在帮助里怎么找不到
求教各位大侠都是怎么学习动网格的啊！
DEFINE_GRID_MOTION(beam,domain,dt,time,dtime)
{
Thread *tf = DT_THREAD(dt);
face_t f;
Node *v;
real NV_VEC(omega), NV_VEC(axis), NV_VEC(dx);
real NV_VEC(origin), NV_VEC(rvec);
real sign;
int n;

/* set deforming flag on adjacent cell zone */
SET_DEFORMING_THREAD_FLAG(THREAD_T0(tf));
sign = -5.0 * sin (26.178 * time);

Message ("time = %f, omega = %f\n", time, sign);

NV_S(omega, =, 0.0);
NV_D(axis, =, 0.0, 1.0, 0.0);
NV_D(origin, =, 0.0, 0.0, 0.152);

begin_f_loop(f,tf)
{
   f_node_loop(f,tf,n)
   {
      v = F_NODE(f,tf,n);
      /* update node if x position is greater than 0.02
         and that the current node has not been previously
         visited when looping through previous faces */
      if (NODE_X(v) > 0.020 && NODE_POS_NEED_UPDATE (v))
         {
         /* indicate that node position has been update
            so that it';s not updated more than once */
         NODE_POS_UPDATED(v);
         omega = sign * pow (NODE_X(v)/0.230, 0.5);
         NV_VV(rvec, =, NODE_COORD(v), -, origin);
         NV_CROSS(dx, omega, rvec);
         NV_S(dx, *=, dtime);
         NV_V(NODE_COORD(v), +=, dx);
         }
   }
}
end_f_loop(f,tf);
}
