Fluent doesn't respect symmetry!

izumi11 · July 8, 2010, 05:36

Hello,
I am doing a Fuel Cell simulation with the fluent PEM module. I have only modeled a quarter of my cell and put two symmetry b.c on each side wall.
For some reason electric current leaks from the sides (which are supposed to be symmetry b.c). Does anyone know the reason?
Thanks

guess what happen History repeat it self.

I have the same problem as you

I am using the Fluent 14 and I want to simulate a PEM fuel cell.
The only tutorial of PEM fuel cell of Fluent is from 6.3 version.
I use it to Fluent 14 and I follow the steps but the results does not the same, also some data and parameters are different.

Anybody know if the tutorial of 6.3 Fluent is working to Fluent 14 too?
I think now you had finish your thesis peacefully.
Can you help me to overcome my problems.
or send me your cas files
Thank you
