编译时 出现如下错误
Linking...

Debug/ISLBM.exe : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.

[自由的好好干活]

extern "C"
{
void Grid_Read();
void Grid_DataDeal();
}
试试

有没把三个文件都加到项目里

Global.h 改一下：

//Global.h 
#include <stdio.h> 
#include <iostream.h> 
#include <math.h> 
#include <stdlib.h> 
#include <iomanip.h> 
#include <time.h> 
#include <malloc.h> 
#include <string.h> 
#include <fstream.h> 


#include "defines.h" 


struct NODE{ 
double x; 
double y; 
double z; 
double rho; 
double P; 
double u; 
double v; 
double w; 
double f[Q]; 
double F[Q]; 

}; 
extern NODE ****node; 
extern int NBLOCK; 
extern int **BLOCK; 

#ifdef __cplusplus
extern "C" {
#end if

void Grid_Read(); 
void Grid_DataDeal(); 

#ifdef __cplusplus
}
#end if

定义时写错了
void Grid_read() ；
改成void Grid_Read() 应该就ok了

楼上的为什么一定非要加extern "C" {} 定义，C++应该可以直接包含的啊。
难道是编译器的不同？？
