hi:

In the course of making udf, i find there is some macros which is never mentioned in the Fluent5.4'guide book or document's CD, except shown in its example. because i a new user who is to add some scalar transport equation into the program and use udf to modify the scalar new the boundary (wall) , so, how can i get the full reference of these macros such as :FLUID_THREAD_P(t0) , if (NULLP(T_STORAGE_R_NV(t0,SV_UDSI_G(P1)))), WALL_TEMP_OUTER(f,thread) and others

Your help is greatly appreciated!

Hi,

are you using interpreted or compiled UDF's? If you are referencing Fluent structures, you need to use compiled UDF's.

Regards,

Lasse

Hi again,

variable and macro documentation is not very good. I think the only way to really determine which variables to use is to look in the header files.

Fluent has a User Services Centre, where you can find a FAQ, documentation and updates. Your license administrator should have a password for that site.

Best regards,

Lasse

FORTRAN RULES OK!
