UDF调试出现一些问题，求帮助！

求是创新

模拟一个弹簧壁面的运动，compiled的时候出现如下错误：

UDF程序如下
#include "udf.h"
static real v_prev = 0.0;
static real f = 120.211498;

    real x[ND_ND];
    real y = 0.0;
    real z = 0.0;

    NV_S(vel, =, 0.0);
    NV_S(omega, =, 0.0);

    force = 0.0;
    begin_f_loop(f,t)

      }

    /* compute change in velocity, that is, dv = F * dt / mass  velocity update using explicit Euler formula */
    y = 0.0161 - z;

    v_prev += dv;
