Help! where to find full UDF Macros and functions
 
Hi,

Could some one tell me where to find the full explanation and definition of function defined by FLUENT? It seems that FLUENT help document does not provide all the information of UDF functions. For example, Property,P_PHASE,M_gravity_P,*fd_function(),C_PHAS E_DIAMETER,RE_NUMBER(),and so on.....

I got this functions and macro from some CFD UDF source code developped by FLUENT staff which is published on FLUENT online help center.

It would be better if we can reach more functions given by FLUENT for our UDF coding.

You're right: the UDF manual is not complete, and this is a problem if you have to develop UDF.

You can find definitions of UDF macros in the header files in the FLUENT directory.

Also, FLUENT organises courses to learn how to develop UDF, but I don't know if they give more documentation if you follow them.

If someome has more info, I'm interested too.

Thanks for response. Yes, I try to find some Macro definition and functions in the SRC directory h files. However, it is boring to search that.Maybe we should ask FLUENT customer supporter to provide some more useful information.

I think they should give a complete list of all available macros.

Hi there,

I have a pdf of the udf user guide, but it is slightly dated (fluent 5). I have been unable to find a fluent 6 user guide and udf guide that i can use, as they are all password protected.

Ive written most of my udf using this guide.

I will forward it onto your email adresses and i hope it is of some help

Good luck

Maybe the thread is a little bit old, but can help something.

It is possible to get in the following link the pdf of Fluent 14 UDF Manual
http://cdlab2.fluid.tuwien.ac.at/LEH...40/flu_udf.pdf

But, as it has been commented, there is a lack of information there. Many functions/macros are not explained; and still they are used in their examples.
Should anyone have a full reference or list of macros, please tell here. We'd be grateful!
