fluent加载第三方(C++,Fortan等)动态链接库_c++6.0怎么导入到ansysfluent中

/ ***********************************************************************

UDF for specifying steady-state parabolic pressure profile boundary

profile for a turbine vane

************************************************************************/

#include "udf.h"

DEFINE_PROFILE(pressure_profile,t,i)

{

   real x[ND_ND]; / * this will hold the position vector */

   real y;

   face_t f;

   begin_f_loop(f,t)

   {

      F_CENTROID(x,f,t);

      y = x[1];

      F_PROFILE(f,t,i) = 1.1e5 - y*y/(.0745*.0745)*0.1e5;

   }

   end_f_loop(f,t)

我们将上面的UDF源代码存为prepare.c

我们启动Fluent 

然后我们直接编译我们刚才保存的prepare.c

我们打开Visual Studio（我是Visual Studio 2013英文版）

#include / *包含输入输出流头文件*/

 

using namespace std;

 

/ *一定要这样写，以c语言的形式导出，在Fluent当中才能识别*/

extern "C" __declspec(dllexport) void CppDynamicLinkLibrary()

{

   cout << "Hello Fluent" << endl; / *输出“Hello Fluent”*/

 

#include "udf.h"

 

/ *链接我们刚才动态链接库的函数*/

extern void CppDynamicLinkLibrary();

 

/ *******************************************

*我们在每次迭代完成以后，

*用动态链接库中的函数输出一次“Hello Fluent”

********************************************/

DEFINE_ADJUST(my_adjust,d)

{

   CppDynamicLinkLibrary(); / *调用动态链接库中的函数*/

将源代码也保存为prepare.c

然后前面动态链接库项目文件夹下

重新打开Fluent 

导入网格，设置好各种求解参数

加载刚才编译的UDF（注意：此处只需要加载（Load），而不需要编译（Build）了！见截图） 

求解运行算例

#

# purpose:

#    This file is the makefile for NT UDF builds.

#

# usage:

#    Change file name 'makefile_nt.udf' to 'makefile'.

#    Place the makefile file in the target dir.

#    Place the helper file 'user_nt.udf' in same directory.

#    Edit user_nt.udf file.

#    Execute an 'nmake'  (no arguments needed).

#

# notes:

#    The user should not need to change this file.

#    The following macros are expected to be in the user_nt.udf file:

#      SOURCES, VERSION, PARALLEL_NODE and USER_OBJECTS.

#    The macro FLUENT_LIB is automatically defined here based on VERSION

#      and PARALLEL_NODE.

#    Only this makefile and the helper file 'user_nt.udf' needs to be

#      the target dir, all other files are automatically generated,

#      and removed in an 'nmake clean'.

#    The source file is expected in ..\..\src directory.

#    Make sure the VC compiler is set up for command line mode, use

#      the file Vcvars32.bat from Visual Studio to assist this.

#    This makefile uses the public domain program 'sed', make sure

#      sed is in your executable path.

#    The '^' char in the SRC literal is a quote for the '\' char,

#      otherwise interpretted as a line continuation char.

#    Use the 'nmake clean' command to restart builds.
