Friends, I am having some problems with F_UDMI - I have never seemed to have much luck with it.

I am using it in a DEFINE_UDS_FLUX(name, f, thread) subroutine. When I put in a

F_UDMI(f, thread, 0) = [a value];

line I get a segmenation violation in fluent gui.

I tried with a C_UDMI using the c0 to the face f and it works, but only for a fixed value, not a variable, so it isn't much good. I would prefer to use the F_UDMI macro anyway.

Is there something fundamental I am missing or is F_UDMI just broken?

Have you enabled the memory with the panel user-defined-memory?Luca

Forgot to mention that, but yes, I have done that.
