Dear friends,

I have been working on fuel cell simulations for a while and I am good at it both fuel cell module and UDS and UDF code to model typical PEM fuel cell. In all my works, I employed 3 dimensional geometry and I faced no problem at all. Recently I started a new work and due to limited access to computational resources, I decided to work on a 2 dimensional geometry. But the problem is when I start running 2d simulation in PEMFC module in Fluent, I receive access violation error as following:

Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

based on my experience in UDF, I know there is something problem regarding PEMFC library code (the problem should be due to pem UDF itself). But, I don't know where exactly the problem comes up.
So, my question is anybody has ever any experience in working 2 dimensional simulation in PEMFC module? If yes, please help me to figure out this problem.

It'll be highly appreciated in advance

Hi，Friend
I've been doing some research on this recently. For the 2D simulation study of PEMEC there were some problems in writing the udf. Did you solve the problems you encountered before?
Can you provide me some help in udf?
Thanks a lot!
