Hello,
I am trying to simulate the 3d single-channel, counter-flow PEM fuel cell model by following the exact steps provided in the tutorial. But, for some reason the simulation stops after 1st iteration giving me "Floating Point Error". I am unable to understand why is this happening. Can anybody please help me out. Thanks in advance.

I had the same error as well. I tried changing the boundary conditions as suggested...However, now it runs for the first two iterations and then the floating point error appears!
Does anyone know what's going on?! Any help or suggestions would be really really appreciated.... |

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 Emad G. elemad1987@gmail.com |
