Scalar Transport and Species Diffusivity UDF's
 
Hi,

I am trying to modify the binary diffusivity for multicomponent species model. I have tried to use define property to specifiy a new binary diffusivity. But I receive an error when I try to implement this UDF into the mixture properties. The error is a type error, what fluent seems to be expecting to get is not what I am passing it. I can provide more specifics if any is able to provide some assistance. As well, I am trying to determine a use a scalar transport to model electrical potentials for a fuel cell model. I would just like to make a contact with someone to bounce some ideas off of. Thanks for you help and this forum has been very helpful just reading previous posts.

Regard,

DH
