1、ANSYS 15.0 fluent udf 环境变量的设置初学 udf,还没进入主题就被 udf 问题搞死了，摸索了一两天终于让我搞出了点名堂，本人用的是 ANSYS 15.0 和 vc 10.0.不多说，先把ANSYS 和 vc 都装上，网上有教程安装的，一步步来别跳步。最好把 vc6 也装一下，因为里面有的东西设置环境变量要用到。先不要打开软件。设置环境变量：1.

3、 Studio 10.0VCbinamd64;C:Program Files (x86)Microsoft Visual Studio 10.0Common7IDE;找个 udf 文件，注意 udf 是支持三维还是二维的，打开 fluent , 设置工作目录。如下：接着就是编译了，不用打开 case 的，直接就可以 define .如果出现什么 xcopy.我们找到 C:WindowsSystem32 里面的 xcopy 复制到C:Program Files (x86)Microsoft Visual Studio 10.0VCbin；C:Program Files (x86)Microsof
4、t Visual Studio 10.0VCbinamd64；如果出现“size_t”: 重定义；不同的基类型，可能是你的 udf 文件有问题。如果实在不行，按照下面的环境变量重新设置一下，重启电脑。INCLUDE C:Program Files (x86)Microsoft Visual Studio 10.0VCinclude;C:Program Files (x86)Microsoft SDKsWindowsv7.0AInclude;LIB C:Program Files (x86)Microsoft Visual Studio 10.0VClibamd64;C:Program File

8、t any detail, the problem is caused because nmake.exe cannot be found. The solution is to start Fluent from the x64 version of the Visual Studio 2013 Command Prompt:1.

14、reason of this error is that previous versions of Visual Studio are 32bit and do not work with your x64 version of Fluent. You probably googled the problem and found advice to start Fluent from the command promt of the SDK (Software Development Kit) 7.0/7.1 instead, or from the command prompt of the
15、 .NET Framework. Unfortunately, as Microsoft states on their website at the Windows SDK 8.1 download page:The Windows SDK no longer ships with a complete command-line build environment. You must install a compiler and build environment separately. If you require a complete development environment that includes compilers and a build environment, you can download Visual Studio 2013, which includes the appropriate components of the Windows SDK.Older versions of the .NET Framework and SDK do not seem to work properly on Windows 8.1 (citation needed, just my experience ). I also found o
