HI Dear

I try with fluent pemfc modul and use tutorial ' modeling a single channel counter flow pem fuel cell . 2007 fluent inc ' but I don't know what the problem is because after first iteration the error message 'floating point error' will appear . I think maybe boundary condition/zones that present in gambit or mesh size are wrong , but I exactly follow the tutorial instruction

so I have 3 questions ,

1- Does anode/cathod side flow channel each one apply 3 faces &1face that remain apply with gdl or they have another definition ?

2- Does anode/cathode side diffusion layer each one apply 3 faces or 4 faces or they have another definition ?

( for ex 2 faces ... interface collector & gdl

1 face ... interface anode/cathode & gdl

1 face interface catalyst & gdl )

3. have you got any idea what my problem is exactly?

BEST REGARD
