I cannot hook DEFINE_DIFFUSIVITY UDF

rumi · September 28, 2018, 08:14

Hi all,

I wrote a code for DEFINE_DIFFUSIVITY udf; however, Fluent cannot hook the function. Compiling UDF was successful and I tried to hook the function on UDS Diffusivity. Since I have two scalars, I did 'define-per-uds'. UDS diffusivity of scalar 0 is constant - it works. However, UDS diffusivity of scalar 1 is supposed to be user-defined. I could load the function, but whenever I press 'okay' button after I select UDF, Fluent does not save this operation as if I haven't selected any UDF code yet.

Please if you know a solution to this, let me know.........

whats your problem? GUI of fluent doesn't work?
in that case you do probably have problems with UDF.

As an other option, you can use TUI commands to apply all settings (you can put TUI commands in journal file and read it)
