help: UDF compile/link error

delft

UDF 就是 fluent帮助中的例子
/**********************************************************************
  unsteady.c
  UDF for specifying a transient velocity profile boundary condition
***********************************************************************/
#include "udf.h"
DEFINE_PROFILE(unsteady_velocity, thread, position)
{
  face_t f;
  real t = CURRENT_TIME;
  begin_f_loop(f, thread)
   
   {
     F_PROFILE(f, thread, position) = 20. + 5.0*sin(10.*t);
   }
  end_f_loop(f, thread)
}
下面是编译时的输出:

哪位高手帮忙看以下? 谢谢

将“ real t = CURRENT_TIME;”改为“real t =RP_Get_Real("flow-time");"试试看。
