i have solved that VOF tutorial in the fluent. but i am getting the error message as

Error:Floating point error:invalid number

Error object) what may be the reason for this.

also i am having some doubts in that,

1. i was not able to understand the meaning of defining a custom field function as 3* radial component.

2. also not able to understand the meaning of patching that custom field function to the water.

--can you please refer the tutorial and clear those doubts

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
