Hi everyone,

I must use MFX to couple ANSYS thermal-electric and CFX. I'm using V12.
What I have done is:
-created a simple geometry (two cilinders, one inside the other one. In the small one I fix the fluid and in the other one a certain voltage on the external surface)
-fixed BCs and loads using ANSYS thermal-electric and exported the .inp file
-tried to convert the .inp file in .cdb file using ANSYS APDL, but it results impossible...
Can you figure out where is the problem? What can I do?

Once that I obtain the .cdb file from the mechanical analysis I must do the same using CFX. But how can I have an .inp file for the fluid part?

Thanks in advance!!!!!!

hi ema.
based on what you said you wanted to do

from your Import data history thread
I sugested to use CFX to do your fluid flow and elecromagnetics and as Glenn said use the standard FSI capabilities to do your mechanical simulation. I have used elecromagnetics in CFX but it does work.

Hi,
thanks for your advices...
I will use CFX, the only problem now is create the surface that has to communicate between mechanical and cfx.
Do you know how can I do that?

with version 12 I thought this would be straightforward with the new fancy dancing flow diagrams so no I haven't done this yet, got too many things to learn in CFX still but I'm sure someone can indicate you how to do this

thanks...
Finally I get it...
but I still dont have heat transfer, I dont know why!!!!!!

I want explain it better...
once that i fix voltage and temperature using the thermal-electric i save the file with the .inp extension; then, using CFX and the ansys multifield external solver coupling,
I can start with my simulation.
the problem is that, even if i have the voltage generation i dont have changes regarding the temperature when i look at the results.
Does someone know why???
