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

Answer 1

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.
