how to get the parameter of eddies in the flow field
 

Dear all,

I want to write a udf program and need the parameters of the eddies in the flow field, like its scale, life time and velocity, etc. But I didn't see the description of this in the HELP document. Could anybody help me with this?

Also, I know that most of the udf of Fluent is written in C language, but now I have a Fortran program in hand, can I put this into the udf of Fluent? Anyone has succeeded in this before, if you have tried it in the Linux system, it will be perfect for me!

Your answer will be much appreciated for any of the questions above, if your answer is complicated, welcome to email me by 865500675@qq.com

Thank you very much! :)
