速度边界问题

jxfsxjxfsx

一个圆球在计算域中心沿y方向一速度为0.5*w*(cos(w*(time-1)))运动.高手看看是否正确.
#include "udf.h"
DEFINE_CG_MOTION(rotate, dt, vel, omega, time, dtime)
{
  Thread *tf;
  face_t f;
  float w =1,y;
vel[1]=0.5*w*(cos(w*(time-1)));}

include "udf.h"
DEFINE_CG_MOTION(rotate, dt, vel, omega, time, dtime)
{
  real w =1;
vel[1]=0.5*w*(cos(w*(time-1)));
}

你这udf拿来能干啥？
