Hello Rob I hope you are fine Can you write udf brownian conductivity for me?
No. We're here to aid, assist, and occasionally moderate. We don't write UDFs or build models.
UDFs may be worked on as part of training, but that requires direct contact through the University to Ansys: look at the "contact us" button on ansys.com
