Hi there,
Iím working with the convective augmentation factor (section 6.3.14.3.6. Augmented Heat Transfer in Ansys Userís guide). Following the instruction, this factor should be assigned using text command.

In fact, I noticed that it can be created as a udf profile. I wonder which UDF function should I use?
I tried to create the following one (just a test case, to see if it can be compiled), but not success.
DEFINE_PROFILE(flux_heat_Augfac, t, i)
{
face_t f;
begin_f_loop(f, t)
{
F_PROFILE(f, t, i) = 20.;
}
end_f_loop(f, t)
}
Am I using the wrong function ? (I didn't find any example in the UDF user's guide.)

UDF is not required if you want to apply a single value or a fixed profile. However, you can use a UDF if the value of augmentation factor changes with the solved field.

Well, in my case, I'm pretty sure it is not a fixed value or a constant. I have to use UDF. Could you please show me an example of UDF on Convective augmentation factor? Thanks a lot.

You can use any general DEFINE_PROFILE UDF, even the one you shared in your post.
