How to use the electric potential model in fluent 17?

roadtodream · June 2, 2016, 08:53

Fluent has added a electric potential model in Version 17.
However its user's manual does not provide any macro that we can use.
How to use the UDF to define the conductivity? How to read the potential in a UDF?

have you load any module with it? i know fluent gives the electrical conductivity field when it loads the fuel cell module.

yes I does load the Electric potential model.
I find in
C:\Program Files\ANSYS Inc\v171\fluent\fluent17.1.0\src\udf\udf.h
and
C:\Program Files\ANSYS Inc\v171\Icepak\icepak17.1\Fluent.Inc\fluent17.1.0 \src\storage\mem.h
but I didn't find any related macros.

I think you should use a DEFINE_PROFILE macro to specify it. Did you try?

That's not the proper methods,as I have some of those and fluent does not show the options( though those profiles are not coded for here).

did you try the DEFINE_DIFFUSIVITY?

Hello Bruno Machado,

I want to show Electric Field in Result, Did I use correct way for doing this? I attached the picture
