DEFINE_CG_MOTION(car_down,dt,cg_vel,cg_omega,t,dtime)          /*下行线car_down列车运行规律*/

            break;
            }
           else
                if(tk[k]<vt&&tk[k+1]>vt)

begin_c_loop(c,t)
       {
        cg_vel[0] = a[m] ;
       }
    end_c_loop(c,t)

else
if(vt<=308)             /*simulation time */

     begin_c_loop(c,t)
       {
         cg_vel[0] = (a[m+1]-a[m])*(vt-tk[m])/(tk[m+1]-tk[m])+a[m] ;
       }
    end_c_loop(c,t)
}
但加载到FLUENT中 的 begin_c_loop(c,t)行出现..\..\src\0428.c(37) : error C2223: left of '->nelements' must point to struct/union
求帮助

数组的下标超界！
如tk[k+1]
