[交流] fluent出现错误Error:received a fatal signal(segmentation fault)

以下是我的程序，求助各位。谢谢 #include"udf.h" #include"stdio.h" #include"mem.h" #include"math.h" #include"dynamesh_tools.h" FILE *fp; real x_cg[ND_ND]; int i; face_t f; Thread *t; DEFINE_CG_MOTION(value,dt,vel,omega,time,dtime) { Thread *thread; Domain *domain; real force[3]={0,0,0};             real moment[3]={0,0,0}; vel[0]=0; for(i=0;i<ND_ND;i++) {         x_cg=DT_CG(dt); } domain=Get_Domain(1); thread=Lookup_Thread(domain,5); fp=fopen("date.txt","a"; Compute_Force_And_Moment(domain,thread,x_cg,force,moment,TRUE); fprintf(fp,"time=%f, force[0]=%f, force[1]=%f\n", time,force[0],force[1]); Message ("time=%f, force[0]=%f, force[1]=%f\n", time,force[0],force[1]); fclose(fp); } DEFINE_PROFILE(inlet_x_velocity,t,position) { face_t f1; begin_f_loop(f1,t) {   F_PROFILE(f1,t,i)=0.5;       } end_f_loop(f,t) } /*向右为正*/
