Fluent高手求教，UDF编写程序，提取一个流场出口个各个参数，然后加载在另一个流场作为入口条件

Posted 2023-05-05

参考技术A 没必要用UDF的，按照下面的操作即可：主要是一个写profile，再在新的case中读取，就ok

1.Write a data profile at the outlet of the old case.
In this step, you will write a file containing selected
ow solution information on
specied surfaces. Later, you will use this information as inlet boundary conditions
when the boiling model is enabled.
File>Write>Profile...

(a) Select Define New Profile in the Options group box.
(b) Select outlet from the Surfaces selection list.
(c) Select Velocity Magnitude, Turbulence Kinetic Energy (k), and Turbulent Dissipation
Rate (Epsilon) and so on from the Values selection list.
(d) Click Write... to open the Select File panel.
(e) Enter liquid-outlet.prof for File Name and click OK.
This writes a profile file to the working folder. The profile file contains the solution
information that was requested in the Write Profile panel. This information
is used to supply inlet information in the boiling calculation.
(f) Close the Write Profile panel.

2..For a new case, Read the newly created profile into memory.
After creating a profile, you need to read it into memory for the profile variables to be
available as boundary conditions.
File>Read >Profile...
FLUENT displays the progress of reading the profile, in the console.本回答被提问者采纳 参考技术B 892222588代做CAE CFD项目

fluent中的UDF能用vs2010编译吗?

我的电脑用的是刚安装的WIN7,下了vs2010程序,用vs编译了UDF 代码后,在fluent导入过程中,出现
"'nmake' 不是内部或外部命令，也不是可运行的程序或批处理文件。"
想请教各位高手这是个什么问题,该怎么解决.
恩，谢谢了，我的邮箱是[e-mail]

当然没有问题,所谓 UDF 编译后就是一个 DLL 文件

使用 nmake 的话，需要先设定环境变量

可以在 cmd 中执行 Path\To\VC\vcvarsall.bat

然后敲 fluent 的启动命令

win7 并没什么特殊，当然可以 参考技术A 给你一个可以解决这个问题的小插件吧，可以不用安装vs，希望可以帮助你，我发你邮箱里啊本回答被提问者采纳
