Hi
I can interpret without error. but during initializing appear the error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.

Although i can Compil it completely but in interaction box donot exist any UDF and fluent give the error:
no udf have been loaded.
Have you suggestion, kindly?

From Fluent help:

In order to hook a DEFINE_MASS_TRANSFER UDF to FLUENT, you must first issue the TUI command solve/set/expert and enter no at the Linearized Mass Transfer UDF? prompt.

You did that? Otherwise I have no idea.

Done.

If I try to interpret it, I see

Error: .\test.c: line 5: parse error.

Don't you get similar lines when you try it? They give hints about what is wrong.

Hi Dear Pakk,
The UDF make error because of writing fr om_index instead of from_index.
I compiled it and that was the only problem.

So keep an eye on those error messages, they give information about where the mistake can be!

hi Djn

To access the TUI in fluent, once your fluent programme is up, key "enter" at the main page. from there, you can then access the tui command.

do this procedure:

1.define->user-defined->functions->interprated..
interprate the ().c file
2.type on the command window of fluent
solve(press enter)
set(press enter)
expert(press enter)
answer for the 4 comming questions respectively are:
no-yes-no-yes

after these 2 steps u can hook the udf from phase intraction->mass tab->user defined->selecting udf...
now you can start runing calculation

let me inform about ur results

Hi. I try your method for hooping a DEFINE_MASS_TRANSFER udf for heta pipe simulation. The udf build and load successfully, but i can't hook it at the phase interaction tab.

Any help is highly appreciated.
